Beneficiation and Metallurgical Process Study for a Gold Mine in Xinjiang

Abstract

The gold deposit in Xinjiang is located in the Kalamailimetallogenic subzone of the northern Junggarmetallogenic belt, with superior geological conditions for gold mineralization. The primary ore is difficult to separate due to its high carbon, arsenic and antimony contents and easy mudding. In the laboratory experiment, the primary ore is leached by granulationand the direct leaching rate is only 16.99%. However, by adopting flotation concentrate- roasting-cyanidation process, a total gold recovery of 73.14% is achieved. The study results show that the combined beneficiation and metallurgy process can make the gold mine reach a higher beneficiation and metallurgy index at areasonable cost.
