Experimental Research of Mineral Processing on a Certain Lead-zinc Oxidize Ore

摘要

A certain multi-metallic lead-zinc oxide ore contains 1.09%Pb, 8.39%Zn. The oxide rate of lead and zinc is 96.34% and 98.15% respectively. In order to recover valuable minerals from the oxide ore comprehensively, the authors adopted priority flotation processing in this experimental research. At last, the lead concentrate with Pb grade of 27.41% and the zinc concentrate with Zn grade of 24.14 % were respectively achieved. The overall recovery of lead was 93.66%, and (he overall recovery of zinc was 90.74%.
