| Abstract: | According to one of Yunnan gold mines,whose gold associate in the pyrite and quartz with fine particle and micro-fine particle,the flowsheet of one stage rougher,one stage scavenging and two stage cleanings is adopted on this condition that grinding fineness is-74 μm75%,T31 as activator,butyl xanthate and A25 as collector.The better results of the gold concentrate grade of 79.30g/t and gold recovery of 89.45% are obtained. |
