Guides For Highsulfide Gold Processing

Mar 17, 2020 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.
