Separation Test of Refractory Lead-Zinc Ore from Myanmar

The paper recovered the lead and zinc from a refractory oxide lead-zinc ore. The grade of lead is 3.97%, with the oxidation rate of 50%.The grade of zinc is 3.37%, with the oxidation rate of 10%.The test made the lead-zinc sulphide flotation first, depressing the zinc mineral and floating the lead mineral, then selected the oxide of lead by sulfidation. The experiment got the best pharmacy system by comparing the species and amount of agent. As a result, the lead sulphide concentrate with a grade of 45.32% and the recovery of 44.86%, the zinc concentrate with a grade of 50.19% and the recovery of 81.23%, the lead oxide concentrate with a grade of 50.37% and the recovery of 45.64% were obtained. Three products had received good indicators, and the issue of lead and zinc interacted with each other had been resolved.
