The first difficulty with cyaniding sulfides is that in a wet environment with oxygen, sulfides tend to oxidize to formsulfuric acid. Acids will destroy the cyanide and create poisonous gases. It is extremely important when treating high sulfide ores with cyanide to keep a sufficient protective base in the solution.

Oct 15, 2016· Sulfuric Acid will "not" dissolve gold. It is used mainly in "electrowinning". You likely know the difference between oxidized gold (free gold, nuggets, flakes, fine particles) and sulfide gold. When gold is locked up as a sulfide, even the cyanide leaching doesn't work to loosen the gold....it needs to be oxidized first. usually byroasting it under intense heat.
