    Zinc is used for the galvanising process, to protect steel in construction, transportation and products It is also used as an alloying element with copper Zinc is produced from ore mining, mineral processing, concentration, roasting, leaching, purification and electrolysisorebearing minerals from the barren rock as much as possible during the mining process In some mining districts, the lead or zinc is found in massive deposits and mined similar to coal using room and pillar methods 612 Lead and Zinc Ore beneficiation Due to low zinc content, runofmine zincbearing ores must be concentrated beforeLead and Zinc EnergyZinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method Secondary (recycled) zinc material, such as zinc oxide, is also processed with the zinc sulfideZinc: smelting, producing and classificationMetalpedia
