How to extract aluminium by electrolysis | Chemistry for All | FuseSchool
 
03:14
Aluminium is the most abundant metal on Earth. However, it is expensive because a lot of electricity is used to extract it. Bauxite is the aluminium ore. It is purified to yield aluminium oxide, which is a white powder. Aluminium is then extracted from aluminium oxide by electrolysis. The aluminium oxide must be made molten so that the ions can pass through it during electrolysis. Aluminium oxide has a very high melting point - over 2000 degrees celsius. So instead of trying to melt it, the aluminium oxide is dissolved in molten cryolite. Cryolite is an aluminium compound with a much lower melting point than aluminium oxide, and so using this reduces some of the costs in extracting aluminium. The steel case is coated with graphite, providing the negative cathode. The positive anodes are immersed in the molten cryolite, and are also made of graphite. When the battery is turned on and electricity flows, the aluminium forms at the negative cathode and sinks to the bottom of the tank where is is tapped off as a pure liquid metal. Oxygen forms at the positive anodes. The oxygen reacts with the carbon of the graphite, forming carbon dioxide. The positive anode therefore burns away, and needs replacing regularly. This is another reason for the extraction of aluminium being so expensive. SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos.

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.

Coltan: Conflict minerals in Congo
 
04:32
Fungamwaka - a mine in the east of Congo. These men work so that we can make telephone calls. They are mining coltan, which is indispensable for the production of mobile phones. The Democratic Republic of Congo is the world’s second-largest supplier of this rare mineral. Fungamwaka is a model mine. There is no child labour, state controls are carried out, taxes are paid. Those in charge of the mine operate legally. And above all there are no militia groups who finance themselves by smuggling resources. The long civil war is the biggest problem in east Congo - funded by the resource wealth in the ground. Ninety percent of the mines are managed by small-scale miners in remote border areas - an El Dorado for rebel groups who demand a share of the yield and sell it the global market via neighbouring countries like Rwanda. The ore is separated from the sand with a shovel, just like in the old gold-digging days. The price of tin has dropped to 5 euros a kilo in the provincial capital; at least coltan still fetches 20 euros. That is why organisations like Misereor have been demanding for a long time that organisations should be legally obliged to ensure that human rights standards are maintained throughout their supply chain from raw materials to finished product- and to cover the costs of this. In Fungamwaka it’s only the miners who pay for the controls- they earn less. www.misereor.org twitter: http://www.twitter.com/misereor

√ Mineral Ores | Metals | Chemistry
 
23:55
#iitutor #Chemistry #Metals https://www.iitutor.com/ The reactivity of a given metal determines the likelihood of finding that metal in the earth's crust in the uncombined elemental form. For some common metals, the likelihood of the metal being found in uncombined elemental form. The likelihood of being found as the uncombined elemental metal is almost the reverse of the activity series. • Minerals are naturally occurring substances, usually compounds, with a definite composition or range of compositions and crystal structures. • Minerals usually contain metals in an oxidised form such as oxides, carbonates, silicates, sulfides and sulfates. • An ore is defined as a naturally occurring deposit that is a mixture of minerals from which a substance, usually a metal, can be economically extracted. • Ores and their constituent minerals form as the result of a variety of geological processes including crystallisation from molten rock, crystallisation from hot aqueous solutions, weathering of older rocks, evaporation from solutions, sedimentation and biological processes. Ores are non-renewable resources formed during the long geological evolution of our planet. Our future use of metals is limited by the finite amounts of accessible natural minerals. There are various economic decisions to be made before an ore body can be developed. The factors that affect the final selling price of the metal include abundance, location, costs of extraction, transportation costs and variations in metal prices. Abundance • The mineral must be sufficiently concentrated in the ore body to make it economical to mine. If the concentration is too low, it may be currently non¬economic, although future improvements in technology can mean that a non-economic ore can become economic. Location • Some regions of Australia are protected for environmental or cultural reasons. Mining cannot be easily conducted it the deposit is located within a high population zone. Costs of extraction • Companies need to determine the cost of mining, milling and extracting the metal from the ore. Aluminium is more expensive to manufacture than copper due to the high costs of the electrolytic process used to make aluminium. Direct cost of extracting metals from their ores Depends on the following: • The activity of the metal. A large amount of energy is used in reducing alumina to aluminium metal because of the stability of the oxide. • Industrial processes used in extraction. Isasmelt is a newer process used in copper ‘matte’ formation which has lowered energy requirements. • Transportation of ores for refining. • The protection of some metals, for example, steel from corrosion, by galvanising. • Reducing costs by recycling, for example, in the aluminium industry. Transportation costs • Consideration must be given to the costs of transporting raw material from the mine to the smelter/refinery as well as the costs of transporting the refined metals overseas Variable metal prices • The world price of metals is constantly varying due to changes in world economies. Mining companies need to make a profit in the long term and the high initial start-up costs and variable metal prices may delay the realisation of that profit. Metals in the Earth’s crust • Most of our metals come from the Earth's crust and a few come from the sea. About three-quarters of the Earth's crust is made up of two non-metals, oxygen and silica. • Aluminium is the most abundant of the metals, but because it is a very active metal it needs large amounts of electricity during the electrolysis process to extract it from its ore, bauxite. It is therefore economic to recycle used aluminium. • Iron is the next most abundant of the metals. It is cheaper to extract from its ore than aluminium. Most is used in steel-making using the basic oxygen steel-making (BOS) process. • If a metal makes up less than 0.001 % of the Earth's crust it is called a scarce metal, for example, copper, zinc, lead, silver, platinum and gold. In some cases a process called 'froth-flotation' is used allowing low-grade ore bodies to be mined more economically. • As prices of minerals rise, conservation and recycling become more attractive options.

The gold rush season find gold resources near your home How to Recycle Scrap Gold Stripper New 2019
 
01:59:40
Hello Friends Today I have a gold plated needle weighing 1.5 kg. I will use Gold Stripper chemicals for this gold extraction. For gold rush people, this does not use all gold. Is a gold plated material. Gold, beautiful color   How much gold is there? I will find this answer. I use 800 ml of water. sodium cyanide 15 gram. Gold Stripper 15 gram. Gold Stripper must work with cyanide. Therefore can dissolve gold.  In most countries, cyanide cannot be used. Gold Stripper is widely used in industrial gold, metal plating. In order to fix the gold plated job and want to remove gold from the work piece. You can see that It will dissolve only gold. It is suitable for the material. Gold plating, thickness not more than 10 microns Water that has gold dissolve will be dirty. You have to filter. In this gold extraction case, use Zinc powder 80 grams or 4 times of quantity of gold. And hope to have gold 20 grams. The first time, we use Zinc powder 50 grams. The second time, we use Zinc powder 30 grams, Potassium Hydroxide 110 grams per a liter of water. The first silt, we use Potassium Hydroxide 80 grams. The second silt, we use Potassium Hydroxide 30 grams. Pour water slowly, be careful Zinc powder flow with water. You can filter only Zinc powder. How to separate gold from zinc powder. I use Nitric acid mixed with water. Ratio Nitric acid 1 water 3. Chemical is very dangerous. You should strictly protect in every step. You have to wear gloves, mask or protective clothing when you work. When extracting gold finish, you must clean thoroughly with water immediately and learn all kinds of chemicals that you used and how thoroughly protected. I brought Sediment gold from zinc powder to boil Nitric acid mixture water. Ratio Nitric acid 3 water 1. To eliminate other metals that are left. Clean gold sediment with hot water 3 times. youtube Subscribe to this ►► https://goo.gl/93XuWY ✔️ THANK YOU ✔️ The Gold Rush find gold resources near your home.

Mining, Ecological Engineering and Metals Extraction for the 21st Century
 
56:03
Speaker: Margarete Kalin, Research Director and President of Boojum Research Ltd. This webinar is an introduction to a recent contribution on sustainable mining, remediation and metal extraction to the Oxford Research Encyclopedia of Environmental Science, Problems and Solutions. Co- authors are M. Kalin, Michael P. Sudbury and Dr. Bryn Harris. The mining industry developed in an age when resources, space and water appeared limitless. A paradigm shift is needed in mining, remediation and extractive metal processes. Human’s insatiable appetite for metals is estimated to produce annually 20 billion tons of waste rock and tailings, covering about 1000 km2 of land. The annual consumption of fresh water is estimated to be about 80 10-9 tons, most of it will be contaminated. A collision course is on the horizon, given shortages of water and arable land and the ever-increasing global population. The key to a solution to the present un-sustainable environmental management practices lays in ecologist’s view of mining wastes as extreme primordial environments. Natural recovery processes can be supported through ecological engineering measures. This starts with exploration and through to operations, ending with decommissioning. By providing physical and chemical support to promote existing ecological processes within the wastes, we can alter the surface of minerals, thereby decreasing contaminant generation and reducing the volume of drainage by promoting run-off. Supporting the growth of indigenous biota leading to increased agglomeration of contaminant on the cell surfaces and upon death the biomass with its contaminants sinks to the sediments. Through bio-mineralization in the sediment, the metals are stabilized, potentially generating in the long-term biogenic ore bodies. All processes are implemented within the mine waste and water management area. Brief examples are given of: -Acid Reduction Using Microbiology through sediment construction; -Alterations of the mineral surface on waste rock reducing sulphide oxidation by effective nutrient supply carried into the wastes by rain and; -Biological polishing “in alkaline and acid mine waste water by a pH adjustment (if needed) and adjusting nutrient imbalances; -Estimates of reductions in waste generation using efficient metals extraction processes. Boojum’s multidisciplinary team of scientists guided by experts of the industry, has laid the foundation for ecological engineering in publications and field demonstration projects. Moving forward we need to evaluate these demonstration project to use the results to build confidence in the approach of ecological engineering, only then can we achieve the paradigm shift needed for the future of the industry. Learn about the speaker: Margarete Kalin is Research Director and President of Boojum Research Ltd. The R& D firm in collaboration with mining companies, the Canadian government and research organizations , has developed and demonstrated an ecological toolkit, that leads to a self-sustaining decommissioned mine waste and water management area. More than 100 scientific publications, numerus chapters in technical books documenting the natural processes and approximately 150 project reports are available on line at http://biblio.laurentian.ca/boojum. Margarete received the Noranda Award for Outstanding Achievements in Land Reclamation from the Canadian Land Reclamation Association and the Teck-Cominco Environmental Award from the Canadian Institute for Mining and Metallurgy (CIM). She was nominated in 2005 as a Distinguished Lecturer by the CIM. She is certified as a QEP (Qualified Environmental Professional ) by the Institute of Professional Environmental Practice and as a Senior Ecologist by the Ecological Society of America. She has been Adjunct Professor at several Canadian universities.

Reupload of a previously uploaded film with improved video & sound. Originally a public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. http://en.wikipedia.org/wiki/Mining Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner. Ores recovered by mining include metals, coal and oil shale, gemstones, limestone, and dimension stone, rock salt and 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 stone and metal has been done 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. The nature of mining processes creates a potential negative impact on the environment both during the mining operations and for years after the mine is closed. This impact has led to most of the world's nations adopting regulations to moderate the negative effects of mining operations. Safety has long been a concern as well, and modern practices have improved safety in mines significantly... Mining in the United States became prevalent in the 19th century, and the General Mining Act of 1872 was passed to encourage mining of federal lands. As with the California Gold Rush in the mid 19th century, mining for minerals and precious metals, along with ranching, was a driving factor in the Westward Expansion to the Pacific coast. With the exploration of the West, mining camps were established and "expressed a distinctive spirit, an enduring legacy to the new nation;" Gold Rushers would experience the same problems as the Land Rushers of the transient West that preceded them. Aided by railroads, many traveled West for work opportunities in mining. Western cities such as Denver and Sacramento originated as mining towns. As new areas were explored, it was usually the gold (placer and then load) and then silver that were taken first, with other metals often waiting for railroads or canals. Coarse gold dust and nuggets do not require smelting, is easy to identify and is easily transported. Modern period In the early 20th century, the gold and silver rush to the western United States also stimulated mining for base metals such as copper, lead, and iron as well as coal. Areas in modern Montana, Utah, Arizona, and later Alaska became predominate suppliers of copper to the world, which was increasingly demanding copper for electrical and households goods. Canada's mining industry grew more slowly than the United States due to limitations in transportation, capital, and U.S. competition; Ontario was the major producer of the early 20th century with nickel, copper, and gold. Meanwhile, Australia experienced the Australian gold rushes and by the 1850s was producing 40% of the world's gold, followed by the establishment of large mines such as the Mount Morgan Mine, which ran for nearly a hundred years, Broken Hill ore deposit (one of the largest zinc-lead ore deposits), and iron ore mines at Iron Knob. After declines in production, another boom in mining occurred in the 1960s and in the 21st century Australia remains a major world mineral producer. Into the 21st century, a globalized mining industry of large multinational corporations has arisen. Peak minerals and environmental impacts have also become a concern. Different elements, particularly rare earth minerals, have begun to increase in demand as a result of new technologies...

What is COBALT?
 
02:16
What is COBALT? Cobalt is a chemical element with symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments (cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was later thought by alchemists to be due to the known metal bismuth. Miners had long used the name kobold ore (German for goblin ore) for some of the blue-pigment producing minerals; they were so named because they were poor in known metals, and gave poisonous arsenic-containing fumes upon smelting. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), and this was ultimately named for the kobold. Today, some cobalt is produced specifically from various metallic-lustered ores, for example cobaltite , but the main source of the element is as a by-product of copper and nickel mining. The copper belt in the Democratic Republic of the Congo, Central African Republic and Zambia yields most of the cobalt mined worldwide. Cobalt is primarily used in the preparation of magnetic, wear-resistant and high-strength alloys. The compounds, cobalt silicate and cobalt aluminate give a distinctive deep blue color to glass, ceramics, inks, paints and varnishes. Cobalt occurs naturally as only one stable isotope, cobalt-59. Cobalt-60 is a commercially important radioisotope, used as a radioactive tracer and for the production of high energy gamma rays. Cobalt is the active center of coenzymes called cobalamins, the most common example of which is vitamin B12. As such, it is an essential trace dietary mineral for all animals. Cobalt in inorganic form is also a micronutrient for bacteria, algae and fungi.
