Research of Refractory Oxidized Lead-Zinc Ore in Lanping

Abstract:

The lead-zinc mine is a low grade of refractory oxide mineral. The grade of lead is 2.84%, with the oxidation rate of 90.95%.The grade of zinc is 3.223%, and with the oxidation rate of 87.9%.The grade of silver is 99.5g/t.This test used the silver-lead sulphide flotation at first, then depressing zinc oxide and floating lead oxide mineral. As a result, in silver-lead sulphide concentrate, the silver grade for 1180 g/t, lead 11.45%. Lead and silver recovery rate were 18.41% and 51.14% respectively. Lead oxide concentrate grade is 32.59%, and the silver is 518g/t. Lead and silver recovery rate were 68.34% and 29.18%. Zinc oxide concentrate grade is 32.65%, including 1.14% lead; zinc recovery rate is 80.11%.
