extraction of nickel using process

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.
