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.

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.

Absorption And Adsorption Adsorption is the adhesion of molecules of gas, liquid, or dissolved solids to a surface. This process creates a film of the adsorbate (the molecules or atoms being accumulated) on the surface of the adsorbent. It differs from absorption, in which a fluid permeates or is dissolved by a liquid or solid. The term sorption encompasses both processes, while desorption is the reverse of adsorption. Similar to surface tension, adsorption is a consequence of surface energy. In a bulk material, all the bonding requirements (be they ionic, covalent, or metallic) of the constituent atoms of the material are filled by other atoms in the material. However, atoms on the surface of the adsorbent are not wholly surrounded by other adsorbent atoms and therefore can attract adsorbates. The exact nature of the bonding depends on the details of the species involved, but the adsorption process is generally classified as physisorption (characteristic of weak van der Waals forces) or chemisorption (characteristic of covalent bonding). Adsorption is present in many natural physical, biological, and chemical systems, and is widely used in industrial applications such as activated charcoal, capturing and using waste heat to provide cold water for air conditioning and other process requirements (adsorption chillers), synthetic resins, increase storage capacity of carbide-derived carbons for tunable nanoporous carbon, and water purification. Adsorption, ion exchange, and chromatography are sorption processes in which certain adsorbates are selectively transferred from the fluid phase to the surface of insoluble, rigid particles suspended in a vessel or packed in a column.

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  is fed to a bank of rougher cells which remove most of the desired minerals as a concentrate. The rougher pulp  passes to a bank of scavenger cells where additional reagents may be added. The scavenger cell froth  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  enters the cell from a conditioner, and flows to the bottom of the cell. Air  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 , while the pulp  flows to another cell. Please like our facebook page http://www.facebook.com/tutorvista

What is NICKEL? 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, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion (passivation). Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's inner core. Use of nickel (as a natural meteoric nickel–iron alloy) 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 the ore for a copper mineral, in the cobalt mines of Los, Hälsingland, Sweden. The element's name comes from a mischievous sprite of German miner mythology, Nickel (similar to Old Nick), who 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 pentlandite and a mixture of Ni-rich natural silicates known as garnierite. Major production sites include the Sudbury region in Canada (which is thought to be of meteoric origin), New Caledonia in the Pacific, and Norilsk in Russia. Nickel is slowly oxidized by air at room temperature and is considered corrosion-resistant. Historically, it has been used for plating iron and brass, coating chemistry equipment, and manufacturing certain alloys that retain a high silvery polish, such as German silver. About 9% of world nickel production is still used for corrosion-resistant nickel plating. Nickel-plated objects sometimes provoke nickel allergy. Nickel has been widely used in coins, though its rising price has led to some replacement with cheaper metals in recent years. Nickel is one of four elements (the others are iron, cobalt, and gadolinium) that are ferromagnetic at approximately room temperature. Alnico permanent magnets based partly on nickel are of intermediate strength between iron-based permanent magnets and rare-earth magnets. The metal is valuable in modern times chiefly in alloys; about 68% of world production is used in stainless steel. A further 10% is used for nickel-based and copper-based alloys, 7% for alloy steels, 3% in foundries, 9% in plating and 4% in other applications, including the fast-growing battery sector. As a compound, nickel has a number of niche chemical manufacturing uses, such as a catalyst for hydrogenation, cathodes for batteries, pigments and metal surface treatments. Nickel is an essential nutrient for some microorganisms and plants that have enzymes with nickel as an active site.

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

In addition, it also illustrates many of the applications of steel mill products. The film is partly animated."

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://en.wikipedia.org/wiki/Steelmaking Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ Steelmaking is the second step in producing steel from iron ore. In this stage, impurities such as sulfur, phosphorus, and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium and vanadium are added to produce the exact steel required. Older processes The earliest means of producing steel was in a bloomery. Early modern methods of producing steel were often labour-intensive and highly skilled arts... An important aspect of the industrial revolution was the development of large-scale methods of producing forgeable metal (bar iron or steel). The puddling furnace was initially a means of producing wrought iron, but was later applied to steel production. The real revolution in steelmaking only began at the end of the 1850s. The Bessemer process was the first successful method of steelmaking in quantity, followed by the open hearth furnace. Modern processes Modern steelmaking processes are broken into two categories: primary and secondary steelmaking. Primary steelmaking uses mostly new iron as the feedstock, usually from a blast furnace. Secondary steelmaking uses scrap steel as the primary raw material. Gases created during the production of steel can be used as a source of power. Primary steelmaking Basic oxygen steelmaking is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel. The process is known as basic due to the pH of the refractories—calcium oxide and magnesium oxide—that line the vessel to withstand the high temperature of molten metal. The process was developed in 1948 by Robert Durrer and commercialized in 1952--1953 by Austrian VOEST and ÖAMG. The LD converter, named after the Austrian towns Linz and Donawitz (a district of Leoben) is a refined version of the Bessemer converter where blowing of air is replaced with blowing oxygen. It reduced capital cost of the plants, time of smelting, and increased labor productivity. Between 1920 and 2000, labor requirements in the industry decreased by a factor of 1,000, from more than 3 worker-hours per tonne to just 0.003. The vast majority of steel manufactured in the world is produced using the basic oxygen furnace; in 2000, it accounted for 60% of global steel output. Modern furnaces will take a charge of iron of up to 350 tons and convert it into steel in less than 40 minutes, compared to 10--12 hours in an open hearth furnace. Secondary steelmaking Secondary steelmaking is most commonly performed in an electric arc furnace. HIsarna steelmaking The HIsarna steelmaking process is a process for primary steelmaking in which iron ore is processed almost directly into steel. The process is based around a new type of blast furnace called a Cyclone Converter Furnace, which makes it possible to skip the process of manufacturing pig iron pellets that is necessary for the basic oxygen steelmaking process. Without the necessity for this preparatory step the HIsarna process is more energy-efficient and has a lower carbon footprint than traditional steelmaking processes...

In this video I have explain about the process of removal of the gangue from the Ore is known as Concentration or Dressing or Benefaction. There are numerous methods of concentration and the methods are chosen based on the properties of the ore. ... Froth Flotation Method: This method is mainly used to remove gangue from sulphide ores. Concentration of ores is important industrial processes and is the first steps to the extraction of the metals. Normally, the ore is concentrated by separating it from the clay body in which it occurs either by gravity, sedimentation, or by a floatation process, before the extraction of the metal from the ore is started.

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/

To make it simple, batteries work by moving electrons from a negatively charged material called an anode to a positively charged material called the cathode, and the device siphons off those electrons to power the device. For instance, nickel cadmium batteries use a nickel oxide cathode and a cadmium anode. Hence the name. This is a chemical process called oxidation that involves an electrolyte layer sandwiched between the electrodes. In the case of the nickel cadmium batteries, they use potassium hydroxide as the electrolyte. But this is a one-shot deal. The chemical reaction releases the electrons, but there’s no way to re-introduce electrons into the equation. So they’re not rechargeable. And for a world increasingly reliant on portable devices, that’s just not good enough. Enter Lithium-Ion batteries, which were developed in the 1970’s by John B. Goodenough. That’s his real name. That’s not a joke. Lithium ion batteries have a cathode made of lithium, duh, and an anode made of carbon, again with an electrolyte between the layers to facilitate the reaction. The difference is lithium will absorb more electrons, so it can be recharged. But it is still a chemical reaction, so it can only reintroduce those electrons at a certain charge rate. Super capacitors work differently. Instead of using a chemical reaction to make electrons flow, also called and electrochemical process, they use static electricity, or an electrostatic process. Now, capacitors have been in our computers for decades, and they work by holding opposite charges between two metallic plates separated by a dielectric material. Super capacitors, as you may have already figured out, are larger versions of capacitors that use a double layer to hold more energy. In fact they’re sometimes called double-layer capacitors. And the cool thing about them is that since the electricity is static and not chemical, there’s far less resistance to the charge. In fact, it’s almost instantaneous. The problem is, they don’t hold that much energy. You need a vast amount of surface area to hold enough energy to make them really useful. So Lithium Ion batteries are very energy dense, meaning they hold a lot more stored energy, but super capacitors are very power dense, meaning the transfer the energy much faster. If, theoretically, you could create super capacitors that could hold as much as a lithium ion battery, you’d have cell phones that could recharge in seconds and it would be good for the rest of the day. And dare we dream it? An EV car that fully charges faster than it takes to pump gas. There is one material that could make this dream a reality. It’s called graphene. Graphene is basically a one-atom thick lattice of carbon atoms that has some ridiculous properties. It’s 200 times stronger than steel, but incredibly light, biodegradable, biocompatible, meaning it can be used in the human body. They say it can be used to desalinate sea water, make space elevators, and form the basis for supercomputers, but for our purposes, it also happens to be one of the most electrically capacitive substances known to man. It has the same energy density as lithium ion batteries with the power density of super capacitors. And since it’s only one atom thick, you can pack a ton of surface area into a small space. With any luck, in the next 10-15 years, we’ll have super capacitor batteries that can handle energy densities at industrial scales giving us quick, plentiful electricity whenever we need it.

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.

What is VACUUM INDUCTION MELTING? What does VACUUM INDUCTION MELTING mean? VACUUM INDUCTION MELTING meaning - VACUUM INDUCTION MELTING definition - VACUUM INDUCTION MELTING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Vacuum induction melting (VIM) utilizes electric currents to melt metal within a vacuum. The first prototype was developed in 1920. One of the only ways to induce a current within a conductor is through electromagnetic induction. Electromagnetic induction induces eddy currents within conductors by changing the magnetic field. Eddy currents create heating effects to melt the metal. Vacuum induction melting has been used in both the aerospace and nuclear industries. Vacuum induction melting uses currents within a vacuum to melt metal. VIM involves placing a core-less induction furnace into a vacuum chamber. The heat used to start the melting process comes from an induced current called an eddy current. The melting and casting operations are then carried out at low pressures to control the entire alloy chemistry process. Eddy currents make the vacuum induction melting process possible. These eddy currents are induced currents in a conductor created by a changing magnetic field. The metals begin to melt after heat is created from the eddy currents. The process becomes simplified to a matter of changing the magnetic field within a conductor. VIM was usually used for refining high purity metal and alloys. VIM is now becoming more popular due to the variety of uses now available. The commercial production of nickel titanium alloys utilizes VIM to its full extent. Other examples of using VIM include melting steels for nuclear applications, cobalt alloy for medical applications, and both high purity copper alloy and clean magnetic alloy for high permeability. The process of VIM can even begin electro-slag remelting, which can remelt electrodes. VIM is the most widely used process for the production of nickel titanium alloys. When producing nickel titanium, the process of VIM using a hot graphite crucible sometimes causes carbon contamination which causes some of the titanium ions to form titanium carbide (TiC). These TiC particles change the transformation temperature along with the strength of the alloy. This is one drawback with the process of vacuum induction melting in graphite.

Low Carbon Silicomanganese Production. Manufacturing Project of Low Carbon Silico Manganese. Production of Ferroalloys. Global Ferroalloys market expected to reach USD 53.5 billion by 2020, expanding at 5.4% CAGR between 2014 and 2020. Low Carbon Silico Manganese which is populary known as LCSiMn is a ferrous alloy with content of carbon, silica and manganese. A large number of steel producing companies extensively demand low carbon silico managanese for reducing total production treatment by using these at the time of slag reduction instead of HCFeMn and decarburization process. Low level carbon silico manganese is extensively appreciated for reducing the lining attack that may cause due to less fluid slag (less MnO). Manganese alloys are mostly used in steelmaking and foundry activities. Manganese is a gray-white metal resembling iron. It is a hard metal and is very brittle, fusible with difficulty, but easily oxidized. Manganese metal and its common ions are paramagnetic. This means that, while manganese metal does not form a permanent magnet, it does exhibit strong magnetic properties in the presence of an external magnetic field.

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).
