Thorsen et al., 1981; Thorsen, 1974 developed a process using Versatic 911 for recovering zinc and other metal values from chloride containing zinc waste such as zinc ash, and flue dusts of zinc smelting. During leaching of the zinc ash, zinc oxide is extracted along with some chlorides which are .
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, iron, because in contrast, zinc has a low boiling 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 ...
