Gold Heap Leaching Process Principle Heap leaching HL is a flexible and economic gold ore processing method used to extract gold from low grade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the gold containing solution is leached.
Copper minerals present difficulties during the cyanide leaching of gold ores leading to excessively high consumption of cyanide and oxygen coupled with low extraction of gold. Copper cyanide species, if present at high levels, adversely affects the downstream processes such as the activated carbon adsorption and the effluent treatment.
