Description of mining of iron aluminum and copper

extraction of aluminum, copper, zinc ampiron video amplesson in this lesson, we 39;re going to discuss the extraction of four metals: aluminum, copper, iron and zinc. in the periodic table, aluminum is a metal of group 13 and copper, iron and zinc are transition metals. in general, metals are extracted from their ore, which is a naturally occurring substance. aluminum is extracted electrolytically, which involves passing electricity through an ionic substance in a solvent with the presence of two rods called electrodes. during the process, the metal gets deposited in one of the electrodes. copper is extracted by the selfreduction method. iron and zinc are both extracted by carbon reduction method from their respective ores. see full list on study aluminum is extracted electrolytically from bauxite, which is aluminum ore. bauxite contains hydrated alumina (al2 o3) with some proportions of iron oxide. the extraction process involves the following steps. a. purification of bauxite this is a twostep process called bayer 39;s process: 1. first, we dissolve bauxite in aqueous sodium hydroxide (naoh) by digestion. bauxite with higher hydroxide contents (al(oh)3) are treated at 120140° c with dilute (3m) naoh and bauxite with higher oxide content (alooh) is treated at a higher temperature (200250° c) and a higher pressure (35 atm) with 57m naoh. 2. next, the insoluble impurities are separated by filtration. al(oh)3 is precipitated by carbon dioxide and ignited to ~1200° c to obtain al2 o3. b. purified bauxite is then dissolved in cryolite, which is 57% caf2 , 57% alf3, 28% al2 o3 and electrolyzed at 950° c in a carbonlined steel cathode with hard carbon rods as the anode. li2 co3is used to (i) lower the melting point of the e see full list on study chalcopyrite (cufes2) is the commonest copper ore. copper is mainly extracted from the sulphide ore (cu2s) by the selfreduction process. the ores are often low grade (0.5% cu) and require concentration (up to 1520% cu). the process contains the following steps. 1. concentration of the ore by froth floatationmethod, where hydrophobic materials are separated from hydrophilic substances. 2. roasting and smelting the sulphide ore is mixed with silica (sio2) at ~1400° c in a reverberatory furnace where impurities like fes are preferentially oxidized prior to cu2 s. 2fes + 3o2 2feo + 2so2 the feo forms slag (stony waste matter separated from metals during the smelting) with silica. the molten mass separates as the top layer of slag (fesio3) and the lower layer is of copper matte mainly composed of cu2s and fes. 3. selfreduction the molten matte is further oxidized in air when the remaining fes is mainly oxidized. more silica is added, which forms more slag with the iron oxide. af see full list on study ore resources on mars magnesium, aluminium, titanium, iron, and chromium are relatively common in them. in addition, lithium, cobalt, nickel, copper, zinc, niobium, molybdenum, lanthanum, europium, tungsten, and g have been found in trace amounts. it is quite possible that in some places these materials may be concentrated enough to be mined economically.
