Experimental Research on Rough Flotation of Lead in Bainiuchang Lead-Zinc Mines

Abstract:

Containing Pb (1.09% ) and Zn (1.97%),the lead-zinc sulphide ore of Bainiuchang mine is a refractory resource in Yunnan Mengzi. The flotation performance of lead is ineffective in plant practice. This research is carried out to enhance the rough flotation performance of lead. With the dosage of lime and zinc sulfate as depressors, sodium hexametaphosphate as dispersant, and ethyl thio carbamate and MA as combined collector, the grinding fineness of 85% , a lead concentrate with lead grade of 17.68%, lead recovery rate of 75.59%, and zinc grade of 7.16% was obtained. The performance of rough flotation of lead is improved.
