Zinc processing: Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products. Zinc (Zn) is a metallic element of hexagonal closepacked (hcp) crystal structure and a density of 7.13 grams per cubic centimetre. It has only moderate
Through this circuit, the ore is slurried with recycled process water and ground to produce fine material of 80% less than 45 microns. Flotation circuit: The slurried ore is then passed onto the flotation circuit where the zinc and lead bearing minerals are separated from the non value minerals. Here, various reagents are introduced which
Lead/Zinc Ore. Lead and zinc often occur in the same ore. Copper is also present in some ores. Froth flotation is again employed to produce marketable concentrates of both. The process is identical in principle to the flotation of other minerals. The figure on the right is
