Abstract

The ore-dressing tests for a native gold ore in Guangxi Province were performed.And by the comparative study of flotation process conditions,the optimum operating conditions of rougher flotation were achieved,which include that:the grinding fineness was-0.075 mm which accounted for 70%,the copper sulfate is 200 g/t,the sodium carbonate is 500 g/t,the water glass is 500 g/t,the butyl xanthate is 60 g/t,the ammonium dibutyl dithiophosphate is 30 g/t,and the 2# oil is 30 g/t.Under the optimal conditions,the closed-circuit tests which are one-stage roughing,two-stage cleaning and two-stage scavenging were performed.Then the gold with the grade of 34.00×10-6 and the recovery of 81.19% can be obtained.
