On the Sulphidation of Anthropogenic Copper Raw Materials with Elemental Sulfur (original) (raw)

The object of this research refers to the sulphidation of mine tailings from Zhezkazgan concentrating mill (ZhCM) and mixed copper ore deposits of Bozschakol. The initial materials used are analysized by X-ray Diffraction. The sulphidation process is carried out at temperature values ranging from 300oC to 800oC aiming to follow the influence of the heat on the process studied. The results show that the interval of 300oC 400oC is the best. The effect of changing the sulphur mass percentage during the sulphidation process is discussed. The reuse of mine tailings to extract valuable metals and the environmental hazards decrease are also investigated.
