| Abstract: | In view of the characteristics of a lead-zinc ore which is featured by the fine dissemination size of lead and zinc minerals,and the close intergrowth of lead,zinc and sulfur minerals,a small test study is carried out.The results show that when the run-of-mine grade of is 1.93% Pb and 3.95% Zn,a lead concentrate with grade 53.06% and recovery rate 75.30%,and a zinc concentrate with grade 47.42% and recovery rate 88.27% are obtained,by applying an efficient selective collector GY-103 to float lead and NO.38 xanthate to float zinc in the flowsheet of sequentially preferential flotation of lead and zinc-rough concentrate regrinding and refined flotation. |
