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.

Key words: micro-disseminated gold ore, flotation, inclusion gold, closed-circuit test
