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.

Sulfide - Wikipedia

Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive.

Recovery of Gold in Pyritic Sulfide Ores - Mine Engineer.Com

Recovery of gold in sulfide ores has fallen into several categories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery.

Many sulfide minerals also contain things like copper or antimony that can react with the cyanide, preventing the cyanide from leaching out the gold and silver. For information on methods to deal with and extract gold, silver and base metals from these refractory ores, I recommend two pages on this website.
