Lead Zinc Mining Process | Equipment | Flow | Cases

In the leadzinc oxide ore, lead is mainly present in the state of leucite and lead bismuth, and zinc is mostly present in the state of smithsonite and willemite. Oxidized ore is gradually formed by the action of longterm weathering and groundwater containing carbonate. Regarding the flotation of leadzinc ore, the lead oxide ore is generally applied by the flotation of xanthate, and the zinc ...
