Research on Leaching of Low Grade Oxidized Copper Ore by Sulfuric Acid

LI Han-pu

Abstract

The tests on leaching of a low grade oxidized copper ore in Yunnan using sulfuric acid have been made.Influence factors on leaching of copper were examined.The experimental results showed that copper leaching of 65% can be obtained under the conditions of room temperature,V(liquid)∶m(solid) of 4 L/kg,sulfuric acid concentration of 30 g/L,leaching time of 50 min,activating agent concentration of 5 g/L.
