Research of refractory Oxidized Lead-zinc Ore in Lanping
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%.
