Lime use in gold processing A review ScienceDirect
网页2021年12月1日 In the leaching circuit, the ore slurry, commonly referred to as “pulp”, is then subjected to leaching in a series of sequential agitated cyanidation tanks, to which cyanide is added and air is sparged into, to enable gold leaching (Adams, 1989). Once solubilized, gold adsorption occurs in a separate series of agitated tanks, in the case of
