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.Biotechnology in minerals processing: Technological,,Sep 01, 2006· Bioleaching of lower grade oxide and secondary sulfide copper ores has become an accepted technology for copper metal recovery.
