Experimental Study on Flotation and Leaching of a Low Grade Gold Ore
In order to rationally develop and utilize a low grade gold mine in Liaoning,the flotation and leaching tests were carried out,and the test results obtained from the leaching test of the ore were better.Under the leaching test conditions of grinding fineness of-0.074 mm accounting for 95.05%,calcium oxide dosage of 1.5 kg/t,pulp concentration of 33%,non-toxic leaching agent dos-age of 4.0 kg/t,and leaching time of 26 h,the leaching rates of gold and silver were 92.60% and 79.43% respectively,which pro-vided a theoretical basis for the rational development and utilization of the ore.
