Abstract

Leaching test on the Oxidized Copper Ore coming from Dishui, XinJiang Province is studied in the NH4CO3-H2O system;Systematic studies are made to show the effects of various factors on the leaching rate of copper. The optimum conditions for leaching is finally confirmed, namely the grinding size is 85% of -0.074mm, concentration of Ammonium carbonate 2mol/L, temperature 45℃, solid to liquid ratio 3:1, stirring intensity 300r/min and leaching time 1.5h. Ultimately, the leaching rate of Cu could reach more than 87%.
