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

Separation of zinc, cadmium and nickel from ZnO–CdO–NiO

May 01, 2012· Highlights ZnO, CdO, and NiO formed chlorides through baking with ammonium chloride. Water leaching was successfully employed for the selective separation of metals. The procedure was used for the treatment of zinc plant purification residues. Baking of real ZPR indicated similar behavior as the mixture of pure oxides. The simulations with STABCAL software appeared to be very reliable.

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 process is in

galvanic or electrolytic cell?? Yahoo Answers

Apr 07, 2008· It is necessary to keep the reactants separate in both types of cells, otherwise the battery will not work. The key difference between them is that galvanic cells work by themselves, while electrolytic cells need energy to work. Also, galvanic cells have a large k value (>1), while electrolytic cells have small k values (<1).
