The gold ore is double-refractory. First, the gold is locked in sulfide mineral particles that must be oxidized to expose the gold for leaching. Second, the ore also contains preg-robbing carbon that will collect solubilized gold from the subsequent leaching circuit if the gold is not first removed.

Abstract Beneficiation of low-grade ore is of critical importance in order to meet the growing demand for coal and mineral industries. But, low-grade ores require fine grinding to obtain the desired liberation of valuable minerals. As a result, production of fine particles makes the beneficiation process difficult through conventional gravity …
