NICKEL AND COBALT ORES: FLOTATION

The nickel content in such sulRde ores is generally low (}3%) and varies from place to place in the same deposit. The low nickel content of the presentday nickel sulRde ores renders them unsuitable for either direct smelting or hydrometallurgical extraction, thus requiring beneRciation. The usual method of nickel extraction from sulRde

Nickel: smelting, producingMetalpedia

Nickel: smelting; Extraction and purifiion; 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 appliions, 75% pure nickel can be used without further purifiion, depending on the composition of the impurities.
