Nickel: smelting, producing-Metalpedia

Nickel: smelting Extraction and purification Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

Extraction of Gold

Lead, bismuth, antimony, cadmium, silver, and mercury also dissolve in presence of air; but copper, iron, aluminium, nickel, cobalt, and zinc dissolve in absence of air. Gold and silver are distinguished by the fact that their maximum solubility corresponds with a very low concentration of the potassium-cyanide solution, a phenomenon probably due to the slight solubility of air in concentrated solutions of this salt.
