Studying on Leaching Low Grade Copper Oxide Ore in the system of NH4CO3-H2O

摘要：

　　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%.
