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, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay

Small scale smelting can be done in a crucible in fact that is what a fire assay is When smelting assays are done on high sulfide ores, a couple of iron nails are added to the mix The metal in the nails reacts with the metals in the sulfides reducing the metals to their metallic state

How Are Metals Extracted From Their Ores? Metal extraction from ores occurs in many different ways involving physical, chemical and electrical means Even ores of the same metal sometimes require different methods of separation depending on the concentration of the metal and its chemical composition within the ore

Therefore much lead ore is obtained as a byproduct of other metal mining, usually zinc or silver Only half of all lead used yearly derives from mining, as half is recovered through recycling, mostly of automobile batteries Besides the ore itself, only a few raw materials are necessary for the refining of lead

cheap and easy to extract a portion of the chromite from a platinum part of their ore feed to the pelletizing plants In the case of the latter process, even more UG2 can be used due to the ore The process is relatively insensitive to the size of its raw The Journal of The South African Institute of Mining and Metallurgy OCTOBER 2004

when ores of aluminium, copper and iron are mined using open cast mining huge pits that scar the landscape are made, creating noise and dust and destroying the habitats of animals and plants+leave waste rock water can be affected as rain drains through exposed ores and slag heaps of waste, ground water can become acidic ores must be processed to extract metals, eg, sulphide ores are
