mineral processing of gold ore

sketches & tables - UNIGE

series of minerals that can carry gold as a physical constituent such as pyrite and arsenopyrite. The mineralogy determines the recovery process of gold. Two types of gold ores can be distinguished: Non refractory ores and refractory ores. Non refractory gold ores permit a straightforward recovery by a relatively simple conventional technology.
