Zinc: smelting, producing and classification-Metalpedia
The global zinc industry is currently experiencing unprecedented interest in new developments and expansions. While most of the new projects and plant upgrades remain committed to traditional processing technologies, recent advances in zinc solvent extraction have created opportunities for new process routes in the treatment of both primary ore and secondary materials. Zinc Mining 80% of zinc mines are located underground, 8% are of the open pit type, with the remainder a combination of both. In terms of production volume, underground mines account for as much as 64% of overall zinc production, combined underground/open pit mines provide 21%, and the remaining 15% is sourced from open pit mines.

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific ... The main raw material in zinc production is zinc sulphide concentrate with about 50-55% Zn. These concentrates will always contain a certain amount of iron, typically in the order of 5-12% Fe, both in the form of pyrite (FeS2) and as the mineral marmatite where iron replaces some of the zinc …
