第 42 卷第 1 期 n beneficiation efficiency were studied. The results showed that the recovery rate of non-toxic leaching
process was only %, and that the gravity separation process has no preferential separation function.
Under the conditions: - mm of grinding fineness with % content, 60 g/t dosage of both collector
isoamyl xanthate and ammonium butyrate black agent, 45% of pulp concentration, 400 g/t dosage of
activator copper sulfate, one roughing one refining two scavenging closed-circuit experiment was carried
out on the raw ore with gold grade of g/t, and the final gold concentrate was g/t. The recovery
rate of gold was %, and the recycling effect was the best.
Key words: gold ore; gravity separation; non-toxic leaching; flotation; rate of recovery
