Zinc: smelting, producing and classification-Metalpedia

Zinc 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.There are two methods of smelting zinc: the pyrometallurgical process and the hydrometallurgical process (over 90% of hydrometallurgical

2017-6-19  oxide can be used as feed for zinc smelters. The zinc oxide product quality range could be 70-85% ZnO, it depends on zinc material feed as other elements and compounds are volatilized with zinc: e.g. lead, cadmium, chlorine, fluorine, sodium and potassium. If needed, a further calcination of the zinc oxide produced can occur in a secondary ...

treatment. The vast majority of smelters use hydrometallurgical process to obtain high-purity zinc products. Roasting – leaching – electrowinning method is well developed, accepting a large range of raw materials and also has economic advantages. However, the problem with this method is the generation of large amounts of leaching residues.

BACKGROUND REPORT PRIMARY ZINC SMELTING

2015-9-10  Zinc ores typically contain three to eleven percent zinc, along with cadmium, copper, lead, silver, and iron. Beneficiation, or the concentration of the zinc in the recovered ore, is accomplished at or near the mine by crushing, grinding, and flotation. Once concentrated, the zinc ore is transferred to smelters for the production of zinc or ...

The Pyrometallurgical process involves the smelting of lead and zinc together as described under “Zinc Smelters”. Lead removed from the Pyrometallurgical process is sent for further refining where it passes through a series of processes to remove impurities. In this process, silver is also produced as a by-product.
