Gold Recovery 101 - Sepro Mineral Systems

Free-Milling Gold Gold ore is considered free-milling when over 90% of the gold can be recovered by a conventional gravity-cyanidation process with low reagent consumptions at a grind size of 80% passing 75 µm. Some examples of free-milling gold ores include quartz-veined deposits and oxidized ores. Sulfide-Associated Gold

A review of the effects of grinding media and chemical ...

The relative exposed surface of sulfide in ore to grinding media can strongly influence the redox conditions in the mill and subsequent flotation behaviour. In the refractory gold ores, solid solution Au can take on oxidation states of 0, 1 Simmons et al., 1999 or even 3 Arehart et al. 1993 .

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.
