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 onposition of the impurities.
