Recovery of Gold in Pyritic Sulfide Ores Mine

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 The fine coating of a iron compound definitely appears to be a key component of the inability of cyanide to efficiently
