Corrosion of zinc in the alkaline electrolyte affects both, primary and secondary zinc-air batteries, because zinc has a more negative reduction potential than hydrogen. This leads to evolution of hydrogen gas on the surface of the zinc particles. The hydrogen evolution reaction is expressed by Equation (1).

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 ...
