Silver Lead Zinc Ore Processing Method using Flotation

Also, the recovery of silver minerals occurring in a lead, zinc sulfide ore is efficiently accomplished using Flowsheet #2. The process consists of selective flotation to produce a mixed silver, lead concentrate for maximum smelter return and a separate zinc concentrate.

Lead/Zinc | METS Engineering

Lead/Zinc. The two primary minerals containing lead and zinc are galena (PbS) and sphalerite (ZnS). These minerals are often found together alongside other sulphide minerals including copper, iron, arsenic, silver and small quantities of gold. Lead and zinc operations process ore through comminution, beneficiation and possible downstream processes.

Zinc - Wikipedia

Zinc oxide is widely used as a white pigment in paints and as a catalyst in the manufacture of rubber to disburse heat. Zinc oxide is used to protect rubber polymers and plastics from ultraviolet radiation (UV). The semiconductor properties of zinc oxide make it useful in varistors and photocopying products.
