Emmerson Resources Ltd (ASX:ERM) managing director Rob Bills speaks to Proactive Investors about the latest news from the Tennant Creek Mineral Field, in Australia's Northern Territory. The explorer and producer holds a lot of land in the area, with a number or projects at various stages of development, from early-stage surveying work through to gold bar production. Bills describes RC drilling results from the Mauretania and West Gibbet prospects as showing, "thick, high-grade intercepts of gold, copper, and also we're seeing some bismuth and cobalt. Fantastic results, some of the best we've seen, certainly the best at West Gibbet." "Excitingly, the drilling has shown that there's a lot of gold quite close to the surface, so it's amenable to open pit mining, which is obviously quite economic... we've also intersected a new zone of mineralisation - ten meters at about 7.6 grams per tonne gold - a bit deeper down, a totally new zone we didn't know was there before. So it opens up that potential of having some shallow high-grade [mining] up higher, and then potentially opportunity for an underground development," explains Bills. Additionally, an airborne geophysical survey of the Northern Corridor at Tennant Creek has been completed, with results due to shore up targets for another drilling campaign next quarter.

What started out as a smaller passion project to showcase all of the incredible outdoor activities at our fingertips in Northern Minnesota has evolved as we learned more about the proposed mining projects in this region and how they might threaten these outdoor activities and freshwater quality for the region/nation. Conversations with Minnesotans across the state began by discussing their favorite outdoor places, but almost inevitably would lead to a discussion of the threats these mines pose to those places. It was these conversations that made it clear that we needed to tell this story about how the sulfide-ore copper mining is threatening these irreplaceable resources. The name of our film comes from the “7th Generation Principle” taught by the Fond du Lac Band of Lake Superior Chippewa that states that in making every decision, be it personal, governmental or corporate, we must evaluate how it will affect our descendants seven generations into the future. In this way, we all must consider the impact these mines will have in Northern Minnesota seven generations from now. 7 Generations is an informative documentary about two proposed sulfide-ore copper mining projects in Northern Minnesota. This film's goal is to inform the public about the dangers of sulfide-ore copper mining in Northern Minnesota. The metal mining industry was named by the EPA as the single largest contributor of toxic pollution in America. Sulfide-ore copper mining has never been done before in Minnesota. While some believe that Minnesota’s long-standing mining history prepares us for this leap, 7 Generations makes clear that the differences between historic mining in Minnesota and modern sulfide-ore mining are vast and insurmountable. Northern Minnesota has a rich history of taconite, or iron ore mining. Many of these mines have operated for decades with little impact to the surrounding waters. This is largely due to the simple process of extracting the iron ore from the surrounding rock. However, the process in sulfide-ore copper mining is more complicated. It involves extracting sulfide-ore from the surrounding rock, which requires washing the sulfide off with water. When this sulfur mixes with water and air, it creates sulphuric acid, which can have devastating effects to human and environmental health if it were to leach into the surrounding groundwater, streams, and lakes. While some see sulfide-ore copper mining as a replacement for the now declining iron mining industry, others see it as a greater threat than it is worth. Because the effects of sulfide-ore copper mining are far-reaching, we've spoken with dozens of people from a wide variety of backgrounds about the risks these mines pose. This includes environmental activists, Native Tribal leaders, medical doctors, biologists, chemists, mining industry professionals, and community leaders. Their stories demonstrate that the multi-faceted threat posted by sulfide-ore copper mining in Minnesota endangers the way of life of an entire region. In order to address this issue with the respect and the thought it deserves, we need to continue holding conversations like these. We intend to interview environmental lawyers, lawmakers, and botanists, in addition to extended interviews with those we've already met with. We intend to use the funding from this Kickstarter to help finance these interviews. We intend to present their stories alongside compelling visuals of Northern Minnesota, as well as archival footage of past mines, in order to present a broad picture of the risks sulfide-ore mining poses for Northern Minnesota and the Great Lakes Region.

Mopani Copper Mines Mopani Copper Mines Plc (Mopani) is a joint venture company based in Kitwe as 95% of its operations are located there, comprising Glencore International AG (73.1%), First Quantum Minerals Ltd. (16.9%) and Zambian Consolidated Copper Mines Limited (10%). Mopani operates the Mufulira mine, smelter, concentrator and copper refinery and the Nkana mine, concentrator and cobalt plant. MCM produced 134,800 tons of copper and 2,040 tons of cobalt in 2003. MCM is investing in a number of oxide copper projects at several of its properties, including an in-situ leaching project at Mufulira and heap leaching at Nkana, and has achieved significant production increases at its underground mining operations in Kitwe and Mufulira. Copper production from internal sources was supplemented by the purchase of some 18,000 tons of copper in high-grade oxide concentrate bought from the Democratic Republic of the Congo. Nkana Mine Nkana mine is one of the largest in Africa, a copper mine located 1 km south-west of Kitwe. The mine is underground as well as open pit and is in operation since 1932 and has produced 6,000,000 tons of copper so far. Its reserves underground include 69,000,000 tons of grading, 16,000,000 tons of copper, and 98,000 tons of cobalt. Its resources include 126,000,000 tons of grading, 43,000,000 tons of copper, and 300,000 tons of cobalt. Copper and cobalt mineralisation occur within the ore shale. Copper mineralisation in the deposits changes from mostly chalcopyrite in the South Orebody, to chalcopyrite-bornite in the Central area and to bornite-chalcopyrite at Mindola. Cobalt occurs as carrollite and cobaltiferous pyrite in approximately equal proportions. The mine produces copper and cobalt from three sources: Mindola Shaft, Central Shaft and South Orebody Shaft. Vertical crater retreat is the predominant mining method while sublevel open-stopping and sublevel caving methods are also used. Other metallurgical facilities, under a management contract by an affiliate of the Anglo American Group, include the Nkana smelter (not owned by Mopani), acid plant (not owned by Mopani) and copper refinery (not owned by Mopani). There is extensive mine tailings around this mine. Nkana Concentrator Nkana Concentrator of Mopani mines, located in Kitwe, treats copper-cobalt sulphide ore using a bulk flotation and segregation flotation flowsheet to produce separate copper and cobalt concentrates. Nkana Concentrator is the most important mineral processing unit of Mopani, as it contributes about 65% of cobalt concentrates treated at the Nkana and Chambeshi Cobalt plants to produce high purity cobalt metal. Konkola Copper Mine Konkola Copper Mine (KCM) is the largest copper mining company in the country. Although based in Chingola, 15% of its operations—namely Nkana Refinery, Nkana Acid Plants and Nkana Smelter (the largest smelter in the nation) -- are located in Kitwe. The Nkana Smelter is the largest primary copper production plant in Zambia. The plant treats concentrates mainly from Nkana, Nchanga, and Konkola mines, which are wholly owned by KCM to produce up to 150,000 tons of new copper. Nkana Smelter The smelter produces high grade anodes, which are electrolytically refined. Sulphur dioxide gas produced by the converters is converted into sulphuric acid which is then used at the Tailings Leach Plant in Nchanga for recovering oxide copper. The smelter also produces discard slag from the reverbs that is rich in cobalt which is stored for future reclamation. This smelter was part of the Konkola Copper Mine's operation at privatisation and has subsequently closed. Nkana Refinery The Nkana Copper Refinery produces electrolytically refined copper in the form of cathodes. The copper meets the LME premium quality grade. The tankhouse has a capacity of about 180,000 tons of finished copper per annum. Nkana Acid Plants There are two single contact sulphuric acid plants at Smelterco, namely the No.3 and No.4 plants. No.3, the largest, is still operational. The plant has a design capacity of 1,050 tons of acid per day. FROM http://en.wikipedia.org/wiki/Mining_in_Zambia

What is ALBION PROCESS? What does ALBION PROCESS mean? ALBION PROCESS meaning - ALBION PROCESS definition - ALBION PROCESS explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. The Albion process is an atmospheric leaching process for processing zinc concentrate, refractory copper and refractory gold. The process is important because it is the most cost-effective method currently in use for extracting both the zinc and lead from concentrates that contain high lead levels (7% or greater). Zinc and lead often occur together and large remaining zinc deposits contain levels of lead that exceed what can be economically extracted through other techniques. The Albion process is not sensitive to the concentration grade and gives favorable recovery with both low grade and dirty concentrates. Environmental impact is also claimed to be mitigated using this technology because in contrast to other methods, sulfur dioxide is not emitted and less energy is consumed over all. Development of the Albion process started during the early nineties led by Mount Isa Mines. It was first patented in 1993. Several pilot plant projects were conducted in 1994 and 1995 which tested the feasibility of using the technology to process high arsenic gold and copper ore. The ore concentrate is first introduced into an IsaMill. This comminution step places a high degree of strain on the mineral lattice and causes an increase in the number of grain boundary fractures and lattice defects of several orders of magnitude. The increase in the number of defects within the mineral lattice "activates" the mineral, facilitating leaching. The rate of leaching is also enhanced, due to the increase in the mineral surface area. The oxidative leaching stage is carried out in agitated tanks operating at atmospheric pressure. Oxygen is introduced to the leach slurry to assist the oxidation. Leaching is autothermal, not requiring any external heat. Temperature is controlled by the rate of addition of oxygen, and by the leach slurry density.

ADELAIDE, AUSTRALIA — A team of Australian researchers may have found a cheap, sustainable way to solve the global problem of mercury contamination. According to The Conversation, the major sources of mercury in Australian waters come from industries involved in water supply and sewage, metal manufacturing, oil and gas extraction, and mining. Mercury pollution seeps into waterways and gets turned into methylmercury by organisms in the water. The toxic substance accumulates in the tissues of seafood and fish, with those at the top of the food chain containing potentially toxic levels, thus exposing people to it mainly through ingestion. As a neurotoxin, methylmercury attacks the brain and nervous system, causing problems for the kidneys and developing fetuses. To combat this, researchers at Flinders University created a sulphur-limonene polymer using two waste products- sulfur and citrus peel — to act as a mercury trap. The dark red material works by attracting mercury, which binds firmly to the polymer, turning it yellow-green in the process. With production costs relatively low, the non-toxic material may be used to coat pipes and as filters, or even in large-scale cleanup operations for heavily contaminated areas, reports Business Insider Australia. ------------------------------------------------------------- Welcome to TomoNews, where we animate the most entertaining news on the internets.

Recent years have seen increased survey and sampling expeditions to the Clarion-Clipperton Zone (CCZ), central Pacific Ocean abyss, driven by commercial interests from contractors in the potential extraction of polymetallic nodules in the region. Part of the International Seabed Authority (ISA) regulatory requirements are that these contractors undertake environmental research expeditions to their CCZ exploration claims following guidelines approved by the ISA Legal and Technical Commission (ISA, 2010). Section 9 (e) of these guidelines instructs contractors to “…collect data on the sea floor communities specifically relating to megafauna, macrofauna, meiofauna, microfauna, nodule fauna and demersal scavengers”. There are a number of methodological challenges to this, including the water depth (4000–5000 m), extremely warm surface waters (~28 °C) compared to bottom water (~1.5 °C) and great distances to ports requiring a large and long seagoing expedition with only a limited number of scientists. Both scientists and regulators have recently realized that a major gap in our knowledge of the region is the fundamental taxonomy of the animals that live there; this is essential to inform our knowledge of the biogeography, natural history and ultimately our stewardship of the region. Recognising this, the ISA is currently sponsoring a series of taxonomic workshops on the CCZ fauna and to assist in this process we present here a series of methodological pipelines for DNA taxonomy (incorporating both molecular and morphological data) of the macrofauna and megafauna from the CCZ benthic habitat in the recent ABYSSLINE cruise program to the UK-1 exploration claim. A major problem on recent CCZ cruises has been the collection of high-quality samples suitable for both morphology and DNA taxonomy, coupled with a workflow that ensures these data are made available. The DNA sequencing techniques themselves are relatively standard, once good samples have been obtained. The key to quality taxonomic work on macrofaunal animals from the tropical abyss is careful extraction of the animals (in cold, filtered seawater), microscopic observation and preservation of live specimens, from a variety of sampling devices by experienced zoologists at sea. Essential to the long-term iterative building of taxonomic knowledge from the CCZ is an “end-to-end” methodology to the taxonomic science that takes into account careful sampling design, at-sea taxonomic identification and fixation, post-cruise laboratory work with both DNA and morphology and finally a careful sample and data management pipeline that results in specimens and data in accessible open museum collections and online repositories. Box core procedures and recommendations are based on the protocols used and developed by the Craig R. Smith Lab, University of Hawaii.

Mel Blanc voices the germs and Milburn Stone (Doc on Gunsmoke TV show) also plays the Doc in this film short.' A doctor's error leads to infection and permanent disability for a serviceman. US Navy Training Film MN-1511L http://en.wikipedia.org/wiki/Bacteria Bacteria (singular: bacterium) constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep portions of Earth's crust. Bacteria also live in symbiotic and parasitic relationships with plants and animals. They are also known to have flourished in manned spacecraft. There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water. There are approximately 5×1030 bacteria on Earth, forming a biomass which exceeds that of all plants and animals. Bacteria are vital in recycling nutrients, with many of the stages in nutrient cycles dependent on these organisms, such as the fixation of nitrogen from the atmosphere and putrefaction. In the biological communities surrounding hydrothermal vents and cold seeps, bacteria provide the nutrients needed to sustain life by converting dissolved compounds such as hydrogen sulphide and methane to energy. On 17 March 2013, researchers reported data that suggested bacterial life forms thrive in the Mariana Trench, which with a depth of up to 11 kilometres is the deepest part of the Earth's oceans. Other researchers reported related studies that microbes thrive inside rocks up to 580 metres below the sea floor under 2.6 kilometres of ocean off the coast of the northwestern United States. According to one of the researchers,"You can find microbes everywhere — they're extremely adaptable to conditions, and survive wherever they are." Most bacteria have not been characterized, and only about half of the phyla of bacteria have species that can be grown in the laboratory. The study of bacteria is known as bacteriology, a branch of microbiology. There are approximately ten times as many bacterial cells in the human flora as there are human cells in the body, with the largest number of the human flora being in the gut flora, and a large number on the skin. The vast majority of the bacteria in the body are rendered harmless by the protective effects of the immune system, and some are beneficial. However, several species of bacteria are pathogenic and cause infectious diseases, including cholera, syphilis, anthrax, leprosy, and bubonic plague. The most common fatal bacterial diseases are respiratory infections, with tuberculosis alone killing about 2 million people per year, mostly in sub-Saharan Africa. In developed countries, antibiotics are used to treat bacterial infections and are also used in farming, making antibiotic resistance a growing problem. In industry, bacteria are important in sewage treatment and the breakdown of oil spills, the production of cheese and yogurt through fermentation, and the recovery of gold, palladium, copper and other metals in the mining sector, as well as in biotechnology, and the manufacture of antibiotics and other chemicals. Once regarded as plants constituting the class Schizomycetes, bacteria are now classified as prokaryotes. Unlike cells of animals and other eukaryotes, bacterial cells do not contain a nucleus and rarely harbour membrane-bound organelles. Although the term bacteria traditionally included all prokaryotes, the scientific classification changed after the discovery in the 1990s that prokaryotes consist of two very different groups of organisms that evolved from an ancient common ancestor. These evolutionary domains are called Bacteria and Archaea...

Crystallization. Food tastes good due to the addition of salt in it. Salt is obtained by the evaporation of seawater. However, this salt is impure and has small crystals. This salt can be converted into pure state by the process of crystallization. Crystallization is the process of formation of large crystals in pure state from their solutions.

Gold is a chemical element with symbol Au and atomic number 79. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental form, as nuggets or grains, in rocks, in veins, and in alluvial deposits. It occurs in a solid solution series with the native element silver and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium . Gold is thought to have been produced in supernova nucleosynthesis, from the collision of neutron stars, and to have been present in the dust from which the Solar System formed. Because the Earth was molten when it was formed, almost all of the gold present in the early Earth probably sank into the planetary core. Therefore, most of the gold that is in the Eart... http://www.wikividi.com ____________________________________ Shortcuts to chapters: 00:03:50: Characteristics 00:05:15: Color 00:06:53: Isotopes 00:08:36: Synthesis 00:10:58: Chemistry 00:15:03: Rare oxidation states 00:17:08: Occurrence 00:22:22: Seawater 00:24:09: History 00:31:41: Etymology 00:32:23: Culture 00:34:36: Mining and prospecting 00:38:24: Extraction and refining 00:39:56: Consumption 00:40:40: Pollution 00:42:56: Monetary use 00:49:01: Price 00:50:03: History 00:54:29: Jewelry 00:56:31: Electronics 00:59:30: Medicine ____________________________________ Copyright WikiVidi.

At the late-onset Pompe disease patient clinic recently held at Duke University, we talked with Karen Kacures about her condition and how it is managed in the two states she lives in - Minnesota and Texas. As Karen explains in this video, she spends her summers in Minnesota and her winters in Texas. And while she prefers the Texas winters to Minnesota’s, she does find that the northern state does have a more organized approach to managing patients with Pompe disease. At the University of Minnesota, the care is a multidisciplinary approach (much like Duke’s) whereas in Texas (in the Austin area), Karen finds that the doctors are not familiar with the condition.

This week we have Dr. Keith Barron as our guest. Keith is an exploration geologist with over 30 years’ experience in the mining sector. In 2001 he privately co-founded Ecuadorean gold explorer Aurelian Resources Inc., which made the colossal Fruta del Norte gold discovery in 2006. He is also the founder of U3O8 Corp, a uranium exploration company. We brought Keith on to get his unique perspective on the uranium sector, at a time when most uranium companies are struggling to keep alive. With the uranium price around $28 - $29 pr. pound, Keith thinks that the bottom is in right now. It's really about the circumstances in Japan and as soon as the first reactor in Japan is turned back on, Keith believes we will see a very quick double in the spot price for uranium. When asked about which other catalysts Keith sees being positive for the uranium price, Keith states that the uranium market has long been in a deficit in regards to supply and demand. The 'Megatonnes to Megawatts' program between Russia and The U.S., ended last year. This will add to the deficit situation. Keith points out that despite Japan turning off all of its nuclear reactors, the country has continued their purchases of uranium. He believes that many investors may see this as creating an oversupply of the fuel. But, Keith says savvy people know that Japan's uranium is going out the back door to China. China is in desperate need of the nuclear fuel to help slow down the pollution in major cities. Next, on the topic of which uranium projects investors should get into... Keith thinks that the wise thing to do is to spread one's exposure between exploration companies, companies going into production, and the large uranium producers. But, it is certainly in the junior companies that investors will be afforded the most leverage. Finally, we ask Keith to talk about Argentina, a jurisdiction where uranium is a preferred source of energy, but has recently defaulted on their debt obligations. He points out that Argentina just signed an agreement with China to build their fourth nuclear reactor. Argentina is now in a situation where they need raw material to run these reactors. It is possible for uranium companies in the country to fill that gap. Since the bond market window will be closed to the country, Keith thinks Argentina will be more open for business. Keith points to U308 Corp as a great option for investors looking to benefit from the imminent rise in spot price. Dr. Barron is an exploration geologist with almost 30 years’ experience in the mining sector. He holds a Ph.D. in Geology from the University of Western Ontario and a BSc. (Hons) in Geology from the University of Toronto. He has worked in more than 20 countries, in North and South America, Africa, Australia, Europe and Asia in the search for gold, silver, diamonds, base metals and industrial minerals. In 2001, he privately founded Ecuador gold explorer Aurelian Resources Inc., which was listed on the TSX-V in 2003 and made the colossal 13.7 million ounce Fruta del Norte gold discovery in 2006. The company was bought by Kinross Gold in 2008 for $1.2 billion. He is also the founder and a Director of South American uranium explorer U3O8 Corp. (UWE:TSX) and a Director of Firestone Ventures (FV:TSX-V). At the PDAC convention in March 2008 he was awarded the Thayer Lindsley International Discovery Award for his role in the discovery of Fruta del Norte and he was also jointly named the Northern Miner’s Mining Man of the Year 2008.

Geoengineering, often referred to as Chemtrails, for the primary purposes of causing severe bodily injury & premature death with malice by the globalist regime, our military & United Nations . the new world order - geoengineering is democide /eugenics being practiced on the American people & population of the planet. There is NO DOUBT this is being done,there are millions of pictures & films of the crimes taking place.& testing has been done on animals,whales,the air,soil,rain,snow,water sources,hair samples world wide to confirm the findings of all the heavy metals found in chemtrails. Geoengineering involves large aircraft constantly spraying tiny particles of aluminum barium,strontium amongst many other harmful toxins, into the air/atmosphere also rat poisoning has been found along with molds & virus's. All people and animals then inhale these toxins while breathing, without informed consent. The toxins also poison the soil and fresh water sources. All Shills & misinformants will not be tolerated & will be blocked & deleted from this page- anyone trying to 'debunk' that geoengineering is taking place is a blatant LIAR or just plain ignorant to the facts. It is well known and documented that long-term exposure to air pollution consisting of particulate matter significantly increases the risk of dying from lung cancer and heart disease. Over many years, the danger of breathing soot-filled air is comparable to the health risks associated with long-term exposure to second-hand smoke. In 2010 alone, 1,200,000 Chinese were killed by particulate air pollution. The principle dangers of inhaling particulate matter applies to smoke and second-hand smoke causing lung cancer; coal miner's lung (anthracosis), a lung disease due to inhalation of coal dust; and baker's lung, inhaling flour and other allergens causes severe asthma. These dangers can be avoided, while Geoengineering particulate fallout can not On a massive scale Geoengineering will likely result in massive democide of the population if not stopped completely. .

The Río Tinto (red river) is a river in southwestern Spain that originates in the Sierra Morena mountains of Andalusia. It flows generally south-southwest, reaching the Gulf of Cádiz at Huelva. This unearthly, reddish river in southwestern Spain is unlike any you've ever seen before. The water gets its coloration from iron dissolved in the water, and is notable for being extremely acidic. This may not sound like a suitable place to find life, but living in the bizarre waters of Rio Tinto are extremophile aerobic microorganisms that feed on the iron and sulphide minerals plentiful in the river. Since ancient times, a site along the river has been mined for copper, silver, gold, and other minerals. In approximately 3,000 BC, Iberians and Tartessians began mining the site, followed by the Phoenicians, Greeks, Romans, Visigoths, and Moors. After a period of abandonment, the mines were rediscovered in 1556 and the Spanish government began operating them once again in 1724. As a possible result of the mining, Río Tinto is notable for being very acidic (pH 2) and its deep reddish hue is due to iron dissolved in the water. Acid mine drainage from the mines leads to severe environmental problems due to the heavy metal concentrations in the river. In 1873, Rio Tinto Company was formed to operate the mines; by the end of the 20th century it had become one of the world's largest multinational mining companies, although it no longer controls the Rio Tinto mines; these are now owned by EMED Mining plc. Scientists now believe that these conditions could be the perfect analogue to what happens when liquid water flows on other planets or moons, such as on Mars or perhaps on Jupiter's moon, Europa. If life can survive under these conditions here on Earth, then it's possible that it also has survived elsewhere, making Rio Tinto an important case study into astrobiology. In fact, data retrieved from NASA's Opportunity rover has shown that similar conditions to those at Rio Tinto have existed on Mars in the past.

Activated carbon, also called activated charcoal, activated coal, or carbo activatus, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Activated is sometimes substituted with active. Due to its high degree of microporosity, just one gram of activated carbon has a surface area in excess of 500 m2, as determined by gas adsorption. An activation level sufficient for useful application may be attained solely from high surface area; however, further chemical treatment often enhances adsorption properties.

These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Mining of stones and metal has been a human activity since pre-historic times. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed. De Re Metallica, Georgius Agricola, 1550, Book I, Para. 1Mining operations usually create a negative environmental impact, both during the mining activity and after the mine has closed. Hence, most of the world's nations have passed regulations to decrease the impact. Work safety has long been a concern as well, and modern practices have significantly improved safety in mines. Levels of metals recycling are generally low. Unless future end-of-life recycling rates are stepped up, some rare metals may become unavailable for use in a variety of consumer products. Due to the low recycling rates, some landfills now contain higher concentrations of metal than mines themselves.
