Refractory Gold Technology

Many gold ores and concentrates contain fine grained gold locked within sulphide minerals, such as pyrite and/or arsenopyrite, unavailable for recovery by conventional leaching. In Sherritt’s gold process, the sulphide and arsenide minerals are completely oxidized by pressure oxidation, thereby liberating the gold.
