Nickel processing | Britannica

Nickel dimethylglyoxime is an insoluble salt useful in analytical chemistry in precipitating nickel. Nickel carbonyl, Ni(CO) 4, a liquid at room temperature, is employed in the carbonyl nickel-refining process. Like all other carbonyls, it is poisonous. Nickel subsulfide, Ni 3 S 2, is the nickel component of matte involved in pyrometallurgy.

Electrolytic Refining - Mineral Processing & Metallurgy

The commercial production of electrolytic metals had its origin a century ago when James Elkington, an English electroplater, invented a process for refining copper electrolytically; later, about 1890, aluminum was first produced on a commercial scale by electrolysis, followed by lead in 1905, nickel in 1910, and zinc about 1915.
