Gold Leaching Process Leaching and Adsorption for Hard Rock Gold Mining The slurry of ground ore and lime moves into a series of six leach tanks 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.

Many pyrite and pyrrhotite minerals contain gold, which is often recovered when extracting copper from lode vein deposits. The purity of gold is stated in terms of fineness and carats (ct). Fineness is defined as the parts per 1000. For example gold with a fineness of 800 means it is 80% pure gold. Alternatively, gold that is pure is 24ct.
