01/01/2020· Additionally, as the copper content of the ore was about 800 times more than its gold , most of the free cyanide ions will be utilized in the copper dissolution process and inhibit Au extraction. Therefore, it will be helpful to leach the copper content of the ore before starting bio cyanidation. This operation is called ore pretreatment and was done by 6 M nitric acid at 25 °C and 25
Several processes can then be used to separate the gold from the ore. Themon techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which
Exploration is followed by excavation, which is followed by crushing and milling to reduce the size of the rocks. This is followed by extraction removing the valuable minerals from the ore and finally refining. Each of these processes are discussed in this chapter.

Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables. Amalgamation with mercury was used to enhance recovery, often by adding it directly to the riffle tables, and mercury is still widely used in small diggings across the world. However, froth flotation processes may also be used to concentrate the gold. In some cases, particularly when the gold is present in the ore as discrete coarse particles, a gravity concentrate can be directly smeltedto for
