Research on the ore-dressing technology of a copper-lead-zinc polymetallic mine in Qinghai
This study investigates the effects of different types of collectors on the flotation separation of copper,lead,and zinc in a polymetallic mine in Qinghai.The emphasis was placed on evaluating the separation efficiency of new types of collectors 4037B,P5100C,and QBSC.The results indicate that P5100C and QBSC are particularly effec-tive for the separation of copper and lead.Under optimal conditions,a process comprising rapid flotation of copper-mixed flotation of copper and lead-regrinding and separation of copper and lead-zinc flotation,yielded a copper concentrate with a grade of 35.56%and a recovery rate of 75.23%,a lead concentrate with a grade of 45.02%and a recovery rate of 71.92%,and a zinc concentrate with a grade of 41.49%and a recovery rate of 72.58%.A mixed concentrate was also obtained with copper grades of 20.14%,lead grades of 8.90%,zinc grades of 28.38%,and recovery rates of 11.93%,6.77%,and 11.81%for copper,lead,and zinc,respectively.The overall copper,lead,and zinc recovery rates were 97.94%,96.62%,and 92.64%,respectively.
