Heap leaching is attractive due to the low capital cost involved, but is a slow process and the gold extraction efficiency is a relatively low 50-75%. In a conventional milling and agitated leaching circuit, the ore is milled in semi-autogenously ball or rod mills until it is the consistency of powder.
Cyanide leaching. After the crushing and grinding stage of the CIL gold mine process, the slurry is added to 9 high-efficiency cyanide leaching tanks arranged in steps. The first 2 gold ore slurry is cyanided first, and the last 6-7 leaching tanks Activated carbon is added while cyanidation is performed for countercurrent adsorption operation.

gold leaching either using the same process at elevated temperature (40–60 C), as patented by the authors, or using a cyanidation process. Copper selective leaching will reduce the gold losses due to a cementa-tion mechanism of gold in the presence of metallic copper as all of the metallic copper will dissolve in the pre-leaching stage.
