equipment for gold from sulfide concentrates

Gold Recovery 101 - Mineral Processing Equipment and Solutions

The ultra-fine gold particles associated with sulfide minerals are often too small to recover by gravity and very expensive to liberate by grinding. Typically, sulfide-associated gold is recovered by froth flotation. A typical sulfide-associated gold flowsheet is presented below in Figure 2: Figure 2: Typical sulfide-associated gold process

Guides For High-sulfide Gold Processing

High sulfide gold ore refers to a certain gold ore with 20% -30% of gold wrapped by sulfide mainly pyrite . Because most of the gold in high-sulfide gold ore exists in the form of sulfide-encapsulated gold, when using direct leaching process, the consumption of gold leaching agent and cost of gold leaching production will increase, and gold processing efficiency is not good.

Gold extraction - Wikipedia

Generally, recovery of the gold from the sulfide concentrates requires further processing, usually by roasting or wet pressure oxidation. These pyrometallurgical or hydrometallurgical treatments are themselves usually followed by cyanidation and carbon adsorption techniques for final recovery of the gold.
