Zinc refining

Zinc refining is the process of purifying zinc to super high grade (SHG) zinc, which is at least 99.995% pure. This process is not usually required when smelting of zinc is done through electrolysis processes, but is needed when zinc is produced by pyrometallurgical processes, because it is only 98.5% pure.

I. The refining and use of zinc The zinc sulphide, called Blende, is the more widespread zinc ore in the zinc mines. The sulfide is roasted at 900 degrees in furnaces for zinc oxide (calcine). Leaching (using sulfuric acid), processed zinc oxide zinc sulphate then removes the iron, gold, silver. Other impurities are then removed by cementation (using zinc powder) such as cadmium, copper, cobalt and nickel, and

Zinc Manufacturing. In the most common hydrometallurgical process for zinc manufacturing, the ore is leached with sulfuric acid to extract the lead/zinc. These pro-cesses can operate at atmospheric pressure or as pressure leach circuits. Lead/zinc is recovered from solution by electrowinning, a process simi-lar to electrolytic refining.
