Synthetic Sulfide Concentrate Dissolution Kinetics in HNO Media.

The nature of tennantite (Cu12As4S13), chalcopyrite (CuFeS2) and sphalerite (ZnS) particles’ mixture dissolution in nitric acid (HNO3) media was investigated in this study. The effects of temperature (323−368 K), HNO3 (1−8 mol/L) and Fe3+ (0.009−0.

Hydrothermal Treatment of Arsenopyrite Particles with CuSO Solution.

The nature of the hydrothermal reaction between arsenopyrite particles (FeAsS) and copper sulfate solution (CuSO) was investigated in this study. The effects of temperature (443-523 K), CuSO (0.08-0.
