Ammonia leaching is a promising method for processing low-grade copper ores, especially those containing large amounts of oxidized copper. In this paper, we study the effect Si-containing minerals on kinetics Cu and Ag from concentrates. The results experiments pressure initial concentrate in an ammonium/ammonium-carbonate solution with oxygen as oxidizing agent are good agreement shrinking core model intra-diffusion mode: case, activation energies were 53.50 kJ/mol 90.35 Ag....
The nature of the hydrothermal reaction between arsenopyrite particles (FeAsS) and copper sulfate solution (CuSO4) was investigated in this study. effects temperature (443-523 K), CuSO4 (0.08-0.96 mol/L) H2SO4 (0.05-0.6 concentrations, time (1-120 min), stirring speed (40-100 rpm) particle size (10-100 μm) on FeAsS conversion were studied. significant at >503 K, it is suggested that characterized by formation a thin layer metallic (Cu0) elemental sulfur (S0) around unreacted core. shrinking...
Autoclave oxidative leaching is one of the most promising hydrometallurgical approaches for copper suplhide materials processing. In previous studies [2–4], possibility an efficient autoclave treatment chalcopyrite concentrate was confirmed. The has following chemical composition, %: 21.5 Cu, 0.1 Zn, 26.5 S, 24.5 Fe, 0.05 Pb, 0.04 Ni, 16.2 SiO 2 [1]. At high temperature conditions (190–200 °C; 4–6 bar) in sulfuric-acid media during 100–120 min about 98% Cu extracted. A residue after POX...
