In the mining industry, lime products are used to refine and condition metal ores and nonferrous metals such as Copper, Zinc, Nickel, Gold, Silver and Aluminum. For this application, lime products are used in the froth flotation of Copper, Nickel and Zinc and are used in Gold and Silver processing to ensure proper pH in the leaching circuit.
Gold mining Wikipedia Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging.
Lime is a calciumcontaining inorganic mineral composed primarily of oxides, and hydroxide, usually calcium oxide and/ or calcium is also the name for calcium oxide which occurs as a product of coalseam fires and in altered limestone xenoliths in volcanic ejecta. The word lime originates with its earliest use as building mortar and has the sense of sticking or adhering.

Neutralization is generally the first step in treating acid mine water (gold, operational and abandoned coal mines). In Gauteng a volume of 240 Mℓ/d of acid mine water from gold mining requires treatment. At an acidity of 3 g/ℓ (as CaCO 3), a lime (CaO) price of R360 and a purity of 93 % the neutralization cost would amount to R57 million/a ...
The slurry (1) of ground ore and lime moves into a series of six leach tanks (2) where a sodium cyanide solution is added. The tanks provide sufficient retention time to allow the gold and silver to be dissolved by the cyanide solution. Oxygen is added to assist in this process. The slurry then moves through a series of carbon adsorption tanks (3).
