Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then reseparates them after their division from other earth materials.
Without thiourea, the final gold extraction reached % at 48 hours and kg/tonne sodium thiosulfate was consumed in this test. In the presence of thiourea, the final gold extraction was % at 48 hours and the consumption of sodium thiosulfate was kg/tonne.

Cyanidation leaching is the primary means of recovery of fine gold and silver. In this process, solutions of sodium or potassium cyanide are brought into contact with an ore which may or may not have required extensive preparation prior to leaching. Gold and silver are dissolved by cyanide in solutions of high pH in the presence of oxygen.

The process was developed for the pretreatment of refractory concentrates ahead of conventional cyanide leaching for gold recovery. As the gold is encapsulated in sulfide minerals such as pyrite and arsenopyrite, the gold is prevented from being leached by cyanide.
The process wastes which are significantly less toxic are characterized as follows: → Waste solids Feed → → Waste solution (effluent) → Waste heat → Waste gases Any potentially hazardous gases released from the gold leaching process are monitored and controlled by neutralization below the legislative requirements.
