gold is a chemical element with the symbol Au and atomic number 79, making it one of the higher atomic number elements that occur naturally. In a pure form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal.chemically, gold is a transition metal and a group element.it is one of the least reactive chemical elements and is solid under mining requires a large amount of water for floatation, heap leaching of copper and gold ores, dust suppression, equipment cooling, slurry transport, and human needs at the mining sites 46. however, mining sites are often far from the water sources and it is not easy to secure the water supply.

metallic sulfide mining is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created threatening to poison the nearby water copper sulphate, blue stone, blue vitriol are all common names for pentahydrated cupric sulphate, which is the best known and the most widely used of the copper salts. uses copper sulphate is a very versatile chemical with as extensive a range of uses in industry as it has in agriculture.
in-situ leaching also called in-situ recovery or solution mining, is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit, in situ.in situ leach works by artificially dissolving minerals occurring naturally in a solid state. for recovery of material occurring naturally in solution, see: brine mining.operating in southwest saskatchewan, canada, the company is the north american market leader in production of high-quality natural sodium sulphate. over domestic and international customers use saskatchewan mining and minerals sodium sulphate in detergents, pulp and paper, glass, starch, industrial enzymes, water treatment and livestock
