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 …

Pickling Steel | American Galvanizers Association
Low-temperature mill scale consists of two iron oxide layers and develops when steel is heated in an annealing or finishing procedure at less than 1070F. Cracks in either type of scale allow the pickling acid to penetrate the scale layers and dissolve the inner layer, causing the bulk of the scale to be removed in flakes.

Extraction of Zinc: Process, Methods, Diagarm, Examples
The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.
