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 highsulfide gold ore exists in the form of sulfideencapsulated 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
