In another, the matte may be roasted to produce high-grade nickel oxides; these are subjected to a pressure leach, and the solution is electro- and carbonyl refined.
Chromium Plating - an overview | ScienceDirect Topics
A. Yli-Pentti, in Comprehensive Materials Processing, 2014 4.11.3.2.1.1 Hexavalent baths. Chromium plating is traditionally made from a solution of chromic acid (CrO 3 which forms H 2 CrO 4 after dissolving in water) and sulfuric acid (H 2 SO 4) using insoluble anodes.The chromium is reduced to metal from the hexavalent state due to the catalytic effect of sulfate ions.

Vats used for chromium plating are of steel with lead lining. Chromic acid is added in solution when required. For nickel plating, the solution is made of 180 – 240 gm of nickel sulfate, 36 gm of nickel chloride and 24 gm of boric acid per 1000 cc of solution. The anode is of pure nickel. Nickel does not deposit well on iron and steel articles.
