Zinc smelting - Wikipedia
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 ...

Zinc recovery from the Waelz kiln was 95% and the zinc oxide produced was directly leached in the zinc smelter which produced zinc metal. The processing of stockpiled Shairmerden zinc oxide ore continues at the smelter although the mine is now closed due to accelerated mining and ore body depletion.
Lead and Zinc Smelting - IFC
Lead and Zinc Smelting. 333. Secondary Lead Processing. The secondary production of lead begins with the recovery of old scrap from worn-out, damaged, or obsolete products and with new scrap. The chief source of old scrap is lead-acid batteries; other sources include cable coverings, pipe, sheet, and other lead-bearing metals. Solder, a tin-based
Zinc: smelting, producing and classification …
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 process is in ...

Lead smelting - Wikipedia
Plants for the production of lead are generally referred to as lead smelters.Primary lead production begins with sintering.Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates. Smelting uses suitable reducing substances that will combine with those oxidizing elements to free the metal.

Zeehan Zinc Slag Project - TartanaResources
The Zeehan smelter operated intermittently from 1898 to 1948 recovering lead, silver and copper from the processing of locally mined ores and ore concentrates. However the technology at that time did not allow for the recovery of zinc and hence the zinc from the processed material ended up in relatively inert zinc slag heaps or dumps on site.
