Froth Floatation Process
 
02:09
Follow us at: https://plus.google.com/+tutorvista/ Check us out at http://chemistry.tutorvista.com/inorganic-chemistry/metallurgy.html Froth Floatation Process Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in several processing industries. Historically this was first used in the mining industry The following steps are followed: 1.Grinding to liberate the mineral particles 2.Reagent conditioning to achieve hydrophobic surface charges on the desired particles 3.Collection and upward transport by bubbles in an intimate contact with air or nitrogen 4.Formation of a stable froth on the surface of the flotation cell 5.Separation of the mineral laden froth from the bath (flotation cell) Simple flotation circuit for mineral concentration. Numbered triangles show direction of stream flow, Various flotation reagents are added to a mixture of ore and water (called pulp) in a conditioning tank. The flow rate and tank size are designed to give the minerals enough time to be activated. The conditioner pulp [1] is fed to a bank of rougher cells which remove most of the desired minerals as a concentrate. The rougher pulp [2] passes to a bank of scavenger cells where additional reagents may be added. The scavenger cell froth [3] is usually returned to the rougher cells for additional treatment, but in some cases may be sent to special cleaner cells. The scavenger pulp is usually barren enough to be discarded as tails. More complex flotation circuits have several sets of cleaner and re-cleaner cells, and intermediate re-grinding of pulp or concentrate. froth flotation cell. Numbered triangles show direction of stream flow. A mixture of ore and water called pulp [1] enters the cell from a conditioner, and flows to the bottom of the cell. Air [2] or nitrogen is passed down a vertical impeller where shearing forces break the air stream into small bubbles. The mineral concentrate froth is collected from the top of the cell [3], while the pulp [4] flows to another cell. Please like our facebook page http://www.facebook.com/tutorvista

What is SHAFT MINING? What does SHAFT MINING mean? SHAFT MINING meaning & explanation

What is SHAFT MINING? What does SHAFT MINING mean? SHAFT MINING meaning - SHAFT MINING definition - SHAFT MINING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Shaft mining or shaft sinking is excavating a vertical or near-vertical tunnel from the top down, where there is initially no access to the bottom. Shallow shafts, typically sunk for civil engineering projects differ greatly in execution method from deep shafts, typically sunk for mining projects. When the top of the excavation is the ground surface, it is referred to as a shaft; when the top of the excavation is underground, it is called a winze or a sub-shaft. Small shafts may be excavated upwards from within an existing mine as long as there is access at the bottom, in which case they are called Raises. A shaft may be either vertical or inclined (between 45 and 90 degrees to the horizontal), although most modern mine shafts are vertical. If access exists at the bottom of the proposed shaft and ground conditions allow then raise boring may be used to excavate the shaft from the bottom up, such shafts are called borehole shafts. Shaft Sinking is one of the most difficult of all development methods: restricted space, gravity, groundwater and specialized procedures make the task quite formidable. Historically mine shaft sinking has been among the most dangerous of all mining occupations and the preserve of mining contractors. Today shaft sinking contractors are concentrated in Canada and South Africa. The most visible feature of a mine shaft is the headframe (or winding tower, poppet head or pit head) which stands above the shaft. Depending on the type of hoist used the top of the headframe will either house a hoist motor or a sheave wheel (with the hoist motor mounted on the ground). The headframe will also contain bins for storing ore being transferred to the processing facility. At ground level beneath and around the headframe is the Shaft Collar (also called the Bank or Deck), which provides the foundation necessary to support the weight of the headframe and provides a means for men, materials and services to enter and exit the shaft. Collars are usually massive reinforced concrete structures with more than one level. If the shaft is used for mine ventilation, a plenum space or casing is incorporated into the collar to ensure the proper flow of air into and out of the mine. Beneath the Collar the part of the shaft which continues into the ground is called the Shaft Barrel. At locations where the Shaft Barrel meets horizontal workings there is a Shaft Station which allows men, materials and services to enter and exit the shaft. From the station tunnels (drifts, galleries or levels) extend towards the ore body, sometimes for many kilometers. The lowest Shaft Station is most often the point where rock leaves the mine levels and is transferred to the shaft, if so a Loading Pocket is excavated on one side of the shaft at this location to allow transfer facilities to be built. Beneath the lowest Shaft Station the shaft continues on for some distance, this area is referred to as the Shaft Bottom. A tunnel called a Ramp typically connects the bottom of the shaft with the rest of the mine, this Ramp often contains the mine's water handling facility, called the Sump, as water will naturally flow to the lowest point in the mine. Shafts may be sunk by conventional drill and blast or mechanised means. The industry is gradually attempting to shift further towards shaft boring but a reliable method to do so has yet to be developed. The shaft lining performs several functions; it is first and foremost a safety feature preventing loose or unstable rock from falling into the shaft, then a place for shaft sets to bolt into and lastly a smooth surface to minimise resistance to airflow for ventilation. In North and South America, smaller shafts are designed to be rectangular with timber supports. Larger shafts are round and are concrete lined. Final choice of shaft lining is dependent on the geology of the rock which the shaft passes through, some shafts have several liners sections as required Where shafts are sunk in very competent rock there may be no requirement for lining at all, or just the installation of welded mesh and rock bolts. The material of choice for shaft lining is mass concrete which is poured behind Shaft Forms in Lifts of 6m as the shaft advances (gets deeper).

Electrolytic Refining of Metals | #aumsum
 
05:28
Our topic for today is Electrolytic Refining of Metals. Electrolytic refining is the process of obtaining pure metals like gold, silver, copper etc. by the process of electrolysis. Let us learn how copper is refined electrolytically. Take acidified copper sulphate solution as the electrolyte. Take a thick rod of impure copper and a thin rod of pure copper. Make impure copper as the anode and pure copper as the cathode. When current is passed through the solution, the CuSO4 electrolyte splits into copper ions and sulphate ions. The copper ions from the electrolyte get attracted towards the cathode. The copper ions gain 2 electrons from the cathode and deposit as pure copper atoms on the thin copper rod. At the same time, the copper atoms from the anode lose 2 electrons, convert into copper ions and dissolve in the electrolytic solution. In this way, indirectly, copper atoms from the anode deposit on the cathode. Hence, size of anode decreases and size of cathode increases. In this way, all the pure copper from the anode deposits on the cathode. The impurities in the impure copper rod settle down as anode mud at the bottom of the container.

Froth Flotation of Ultramafic Nickel Ore - No Pre-treatment
 
01:11
https://www.researchgate.net/publication/241091320_Processing_an_ultramafic_ore_using_fiber_disintegration_by_acid_attack Ultramafics are one of the three major sources of Nickel. The other two are sulphides and laterites. Because of decreasing sulphide ore sources and the cost of treating laterites, increasing attention is directed to the third source, Ultramafic ores. A huge Nickel resource in Ultramafic hosted rocks are available in 'Thompson Nickel Belt' located in north central Manitoba. Similar ore bodies in a considerable amount have also been reported to be existed in Quebec, Western Australia, North Central China and Zimbabwe. The major processing challenge is posed by the serpentine polymorph chrysotile, the dominant part of this ore. Being fibrous in nature, chrysotile creates physical entanglement which in turn reduces selectivity and hinders bubble motion during flotation. In this video you can compare the froth phase of a common sulphide ore to the Ultramafic one. Froth phase seems lack of shiny sulphide particles in case of Ultramafic ore reveals no separation between sulphides and silicates. https://www.researchgate.net/publication/241091320_Processing_an_ultramafic_ore_using_fiber_disintegration_by_acid_attack

How Does Electroplating Work | Chemistry for All | FuseSchool
 
05:49
Learn the basics about electroplating. The anode is positively charged, and the cathode is negatively charged. They are immersed in a solution called an electrolyte. The electrolyte and the anode are selected based upon the material that you are electroplating with. So if you want to create a copper plate on the cathode, you would use a copper anode and a copper based electrolyte solution. When the battery is turned on, the positively charged ions in the electrolyte are attracted to the cathode. Here, they gain electrons which is known as reduction. When the battery is turned on, the negatively charged ions in the electrolyte solution are attracted to the anode. The atoms within the anode, so the copper atoms in copper plating, lose electrons which is known as oxidation. These copper atoms are now positively charged and dissolve into the electrolyte solution. Once in the electrolyte solution, because they are now positively charged they are attracted over to the negative cathode. Hence electroplating the cathode. The electrons flow from the anode to the cathode. Half equations occur at each anode, with oxidation at the anode and reduction at the cathode. Just remember, oxidation is loss of electrons and reduction is gain. SUBSCRIBE to the Fuse School YouTube channel for many more educational videos.

Easy Nickel And Copper Electroplating Method

Simple, cheap, and reliable way to plate metals. I used this method to plate the screens in my Edison Battery... Check my page at: http://www.noonco.com/nickel/ For FAQs and less expensive alternatives. Just in: I see that Amazon has Nickel Ammonium Sulfate for only $21 for 100 grams. The address I found was: http://www.amazon.com/Ammonium-Sulfate-Laboratory-Hazardous-Chemical/dp/B008V5ZFB0/ref=sr_1_3?ie=UTF8&qid=1390583233&sr=8-3&keywords=nickel+ammonium+sulfate SPECIAL NOTE: A lot of viewers have written to say that the MSDS lists nickel salts as carcinogenic, but I have not had a high degree on concern because I also see many other common items listed as similar carcinogenic risks. These include Diesel exhaust, gasoline, paint fumes, plastic glue, lighter fluid, lead and many others. So I believe with care, most of these can be handled safely. Please be cautious and respectful of any chemical. It's not worth it to get hurt. 3 G's: Goggles, gloves and good ventilation... P.S. After many suggestions that I experiment with less expensive Nickel Sulfate, I've found a less expensive chemical combo that also makes a fantastic and shiny coat! I have this up for you at www.noonco.com/nickel Thought I'd pass it on. :-) P.S. For those interested in the Edison Battery, check out my pages at: http://www.noonco.com/edison/

"Nickel" is a chemical element with symbol "Ni" and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel shows a significant chemical activity that can be observed when nickel is powdered to maximize the exposed surface area on which reactions can occur, but larger pieces of the metal are slow to react with air at ambient conditions due to the formation of a protective oxide surface. Even then, nickel is reactive enough with oxygen that native nickel is rarely found on Earth's surface, being mostly confined to the interiors of larger nickel–iron meteorites that were protected from oxidation during their time in space. On Earth, such native nickel is found in combination with iron, a reflection of those elements' origin as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's inner core. The use of nickel has been traced as far back as 3500 BCE. Nickel was first isolated and classified as a chemical element in 1751 by Axel Fredrik Cronstedt, who initially mistook its ore for a copper mineral. The element's name comes from a mischievous sprite of German miner mythology, Nickel , that personified the fact that copper-nickel ores resisted refinement into copper. An economically important source of nickel is the iron ore limonite, which often contains 1-2% nickel. Nickel's other important ore minerals include garnierite, and pentlandite. Major production sites include the Sudbury region in Canada , New Caledonia in the Pacific, and Norilsk in Russia. Wiz Science™ is "the" learning channel for children and all ages.

Applications Extraction of iron from its oxides:In a Blast furnace Oxide ores of iron, after concentration through calcination/roasting are mixed with limestone and coke are fed from its top.Hot air is blown from the bottom of the furnace and coke is burnt to give temperature upto about 2200K in the lower portion itself. The burning of coke therefore supplies most of the heat required in the process and will be oxidised to CO. The CO and heat moves to upper part of the furnace. In upper part, the temperature is lower and the iron oxides (Fe2O3 and Fe3O4) coming from the top are reduced in steps to FeO. Limestone is also decomposed to CaO which removes silicate impurity of the ore as slag. The slag is in molten state and separates out from iron.Equation here for lime stone. Thus, the reduction reactions taking place in the lower temperature range and in the higher temperature rangedepend on the points ofcorresponding intersections in the ΔrG minus verses T plots. These reactions can be given as follows:At 500 -- 800 K lower temperature range in the blast furnace. 3 Fe2O3 + CO gives 2 Fe3O4 + CO2 equation 11. Fe3O4 + 4 CO gives 3Fe + 4 CO2 equation 12. Fe2O3 + CO gives 2FeO + CO2 equation 13. At 900 -- 1500 K higher temperature range in the blastfurnace:C + CO2 gives 2 CO equation 14. FeO + CO gives Fe + CO2 equation 15. The iron obtained from Blast furnace contains about 4% carbon and manyimpurities in smaller amount (e.g., S, P, Si, Mn).

This separation technique can be useful in mining iron as it is attracted to a magnet. In mines where wolframite was mixed with cassiterite, such as South Crofty and East Pool mine in Cornwall, magnetic separation was used to separate the ores. At these mines a device called a Wetherill's Magnetic Separator (invented by John Price Wetherill, 18441906) was used. In this machine the raw ore, after calcination was fed onto a moving belt which passed underneath two pairs of electromagnets under which further belts ran at right angles to the feed belt. The first pair of electromagnets was weakly magnetised and served to draw off any iron ore present. The second pair were strongly magnetised and attracted the wolframite, which is weakly magnetic. These machines were capable of treating 10 tons of ore a day which is a lot of ore. Please like our facebook page http://www.facebook.com/tutorvista

Hydrogen and Fuel Cells | Chemistry for All | FuseSchool
 
05:01
We are trying to design a way to power vehicles of the future by using the hydrogen that is stored as a fuel cell for Motor Vehicles in order to obtain energy for the vehicle we need to rejoin the hydrogen with oxygen and this is done most efficiently in what is called a fuel cell in an ordinary electric cell a metal say zinc ionizes at one electrode the anode giving off two electrons the electrons are pushed around the circuit carrying energy - for example a motor and absorbed by metal ions of a less reactive metal say copper the circuit is completed by the movement of metal ions through the solution in a fuel cell the reactants are gases instead of metals hydrogen gives its electrons the electrons flow round driving the motor and arrive at the cathode where they are recombined with hydrogen in the presence of the reactive gas oxygen which provides the driving energy to form water again the electrodes can be made of porous carbon coated with a catalyst such as platinum or nickel advantage of combining a fuel and oxygen In a Cell is that you can in theory convert most of the chemical energy to electricity whereas burning them has happens in the internal combustion engine of a car has a maximum efficiency of about 50% and in practice only about 25% of the chemical energy does useful work in driving the engine the rest comes out as waste heat there are two major problems to using hydrogen fuel cells in vehicles firstly where do you get the hydrogen currently most industrial hydrogen is derived from methane and the carbon is rejected as carbon dioxide thus adding to the greenhouse effect the hope is that we can learn to mimic photosynthesis by using sunlight to split water molecules apart giving us a clean and simple source of hydrogen currently this is achieved by using photo voltaic cells to generate electricity which then electrolyte is water forming hydrogen and oxygen to take the analogy further the hydrogen is transported to the fuel cell like biomass passing along a food chain and the oxygen which we tend to take for granted is vented to the atmosphere the fuel cell then gets its oxygen from the atmosphere just like in respiration the energy is stored whilst the hydrogen and oxygen are kept apart the other problem is how to store and transport the hydrogen gas, once you've got it it's extremely difficult to liquefy and rather dangerous if kept as a gas under pressure particularly if the vehicle crashes research is therefore focusing on hydroxides compounds of elements with hydrogen which are solid or liquid at room temperature and which give out their hydrogen reversibly and without too much energy input this allows hydrogen to be pumped in reacting to form the hydroxide. Then on the journey the hydrogen is given off to be used in the fuel cell to drive the vehicle for example ammonia and borane a solid at room temperature with the same structure of ethane gives up its hydrogen on heating however it will probably be more energy efficient to run the cars on batteries which are charged from green electricity SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos.

Iron Making Process
 
03:28
Iron is one of the most common elements on earth. Nearly every construction of man contains at least a little iron. It is also one of the oldest metals and was first fashioned into useful and ornamental objects at least 3,500 years ago. Pure iron is a soft, grayish-white metal. Although iron is a common element, pure iron is almost never found in nature. The only pure iron known to exist naturally comes from fallen meteorites. Most iron is found in minerals formed by the combination of iron with other elements. Iron oxides are the most common. Those minerals near the surface of the earth that have the highest iron content are known as iron ores and are mined commercially. Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements. Pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing the carbon content and adding other elements such as manganese and nickel to give the steel specific properties. The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less. Coke is a substance made by heating coal until it becomes almost pure carbon. Sinter is made of lesser grade, finely divided iron ore which, is roasted with coke and lime to remove a large amount of the impurities in the ore. Limestone occurs naturally and is a source of calcium carbonate. Other metals are sometimes mixed with iron in the production of various forms of steel, such as chromium, nickel, manganese, molybdenum, and tungsten.

Extraction of zinc
 
13:51
Useful for CBSE, ICSE, NCERT & International Students Grade 12 Subject: Chemistry Lesson :General Principles and Processes of Isolation of Elements Topic: Extraction of zinc Zinc is a transition metal that occurs in the center of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The space between Groups 2 and 13 is occupied by the transition metals. These metals share many physical and chemical properties in common. Alloys and compounds of zinc have been known since at least 500 B.C. But zinc metal was not known or used until much later. The reason is that zinc boils away or vaporizes easily when heated. Any effort to release zinc from its compounds also causes the metal to evaporate into the air.

What is SPOT WELDING? What does SPOT WELDING mean? SPOT WELDING meaning - SPOT WELDING definition - SPOT WELDING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Resistance spot welding (RSW) is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current. Work-pieces are held together under pressure exerted by electrodes. Typically the sheets are in the 0.5 to 3 mm (0.020 to 0.118 in) thickness range. The process uses two shaped copper alloy electrodes to concentrate welding current into a small "spot" and to simultaneously clamp the sheets together. Forcing a large current through the spot will melt the metal and form the weld. The attractive feature of spot welding is that a lot of energy can be delivered to the spot in a very short time (approximately 10–100 milliseconds). That permits the welding to occur without excessive heating of the remainder of the sheet. The amount of heat (energy) delivered to the spot is determined by the resistance between the electrodes and the magnitude and duration of the current. The amount of energy is chosen to match the sheet's material properties, its thickness, and type of electrodes. Applying too little energy will not melt the metal or will make a poor weld. Applying too much energy will melt too much metal, eject molten material, and make a hole rather than a weld. Another feature of spot welding is that the energy delivered to the spot can be controlled to produce reliable welds. Projection welding is a modification of spot welding. In this process, the weld is localized by means of raised sections, or projections, on one or both of the workpieces to be joined. Heat is concentrated at the projections, which permits the welding of heavier sections or the closer spacing of welds. The projections can also serve as a means of positioning the workpieces. Projection welding is often used to weld studs, nuts, and other screw machine parts to metal plate. It is also frequently used to join crossed wires and bars. This is another high-production process, and multiple projection welds can be arranged by suitable designing and jigging. Spot welding is typically used when welding particular types of sheet metal, welded wire mesh or wire mesh. Thicker stock is more difficult to spot weld because the heat flows into the surrounding metal more easily. Spot welding can be easily identified on many sheet metal goods, such as metal buckets. Aluminium alloys can be spot welded, but their much higher thermal conductivity and electrical conductivity requires higher welding currents. This requires larger, more powerful, and more expensive welding transformers. Perhaps the most common application of spot welding is in the automobile manufacturing industry, where it is used almost universally to weld the sheet metal to form a car. Spot welders can also be completely automated, and many of the industrial robots found on assembly lines are spot welders (the other major use for robots being painting). Spot welding is also used in the orthodontist's clinic, where small-scale spot welding equipment is used when resizing metal "molar bands" used in orthodontics. Another application is spot welding straps to nickel–cadmium or nickel–metal hydride cells to make batteries. The cells are joined by spot welding thin nickel straps to the battery terminals. Spot welding can keep the battery from getting too hot, as might happen if conventional soldering were done. Good design practice must always allow for adequate accessibility. Connecting surfaces should be free of contaminants such as scale, oil, and dirt, to ensure quality welds. Metal thickness is generally not a factor in determining good welds. ....

Electrochemical Cells An electrical battery is a combination of one or more electrochemical cells, used to convert stored chemical energy into electrical energy. Since the invention of the first Voltaic pile in 1800 by Alessandro Volta, the battery has become a common power source for many household and industrial applications. According to a 2005 estimate, the worldwide battery industry generates US$48 billion in sales each year, with 6% annual growth. Batteries may be used once and discarded, or recharged for years as in standby power applications. Miniature cells are used to power devices such as hearing aids and wristwatches; larger batteries provide standby power for telephone exchanges or computer data centers. The name "battery" was coined by Benjamin Franklin for an arrangement of multiple Leyden jars (an early type of capacitor) after a battery of cannons. Strictly, a battery is a collection of two or more cells, but in popular usage battery often refers to a single electrical cell. An early form of electrochemical battery called the Baghdad Battery may have been used in antiquity.] However, the modern development of batteries started with the Voltaic pile, invented by the Italian physicist Alessandro Volta in 1800.

What is SLURRY PIPELINE? What does SLURRY PIPELINE mean? SLURRY PIPELINE meaning - SLURRY PIPELINE definition - SLURRY PIPELINE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. A slurry pipeline is a specially engineered pipeline used to move ores, such as coal or iron, or mining waste, called tailings, over long distances. A mixture of the ore concentrate and water, called slurry, is pumped to its destination and the water is filtered out. Due to the abrasive properties of slurry, the pipelines can be lined with high-density polyethylene (HDPE). Slurry pipelines are used as an alternative to railroad transportation when mines are located in remote, inaccessible areas. The concentrate of the ore is mixed with water and then pumped over a long distance to a port where it can be shipped for further processing. At the end of the pipeline, the material is separated from the in a filter press to remove the water. This water is usually subjected to a waste treatment process before disposal or return to the mine. Slurry pipelines offer an economic advantage over railroad transport and much less noise disturbance to the environment, particularly when mines are in extremely remote areas. Pipelines must be suitably engineered to resist abrasion from the solids as well as corrosion from the soil. Some of these pipelines are lined with high-density polyethylene (HDPE). Typical materials that are transferred using slurry pipelines include coal, copper, iron, and phosphate concentrates, limestone, lead, zinc, nickel, bauxite and oil sands. Slurry pipelines are also used to transport tailings from a mineral processing plant after the ore has been processed in order to dispose of the remaining rocks or clays. For oil sand plants, a mixture of oil sand and water may be pumped over a long distance to release the bitumen by ablation. These pipelines are also called hydrotransport pipelines. Early modern slurry pipelines include The Ohio 'Consolidation' coal slurry pipeline (1957) and the Kensworth to Rugby limestone slurry pipeline (1965) The 85 km Savage River Slurry pipeline in Tasmania, Australia, was possibly the world's first slurry pipeline to transport iron ore when it was built in 1967. It includes a 366m bridge span at 167m above the Savage River. It carries iron ore slurry from the Savage River open cut mine owned by Australian Bulk Minerals and was still operational as of 2011. One of the longest slurry pipelines was to be the proposed ETSI pipeline, to transport coal over a distance of 1036 miles (1675 km). It was never commissioned. It is anticipated that in the next few years some long distance slurry pipelines will be constructed in Australia and South America where mineral deposits are often a few hundred kilometers away from shipping ports. A 525 km slurry pipeline is planned for the Minas-Rio iron ore mine in Brazil. Slurry pipelines are also being considered to de-silt or remove silts from deposits behind dams in man-made lakes. After the Hurricane Katrina disaster there were proposals to remedy the environment by pumping silt to the shore. Proposals have also been made to de-silt Lake Nubia-Nasser in Egypt and Sudan by slurry pipelines, as Egypt is now deprived of 95% of its alluvium, which used to arrive every year. These projects to remedy the environment might alleviate one of the major problems associated with large dams and man-made lakes. ESSAR Steel India Limited owns two 250 km+ slurry pipelines in India; the Kirandul-Vishkhapatnam (slurry pipeline) and Dabuna-Paradeep pipeline.
