Iron Control in Zinc Pressure Leach Processes

The occurrence of zinc in sulfide ore deposits is generally accompanied by various iron minerals Hence even the most efficient concentrators generally produce a zinc concentrate with significant iron content The efficient recovery of zinc metal from zinc concentrates requires the rejection of iron residue in a form that minimizes the zinc
