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 plant''s primary recovery unit, the LowG Centrifuge concentrator is a fine gold recovery system, however, for "course gold ores", we install a "jackpot" system to recover coarse gold and nuggets before the classified ore feeds into the primary recovery unit.
Yet, dry methods do work well enough that they can produce gold well if the ground is rich enough. Recent developments in dry washing equipment have made it possible for a one or twoman operation to work larger volumes of dry placer ground without water, and obtain good results in gold recovery.

The common definition of "refractory" gold ores, are those ores that do not allow the recovery of gold by standard gravity concentration or direct cyanide leaching. One major category of refractory ores are gold values contained within the crystalline structure of sulfide minerals such as pyrite and arsenopyrite.
