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.

The feasibility of processing lowgrade coppernickel ores by heap bioleaching was investigated. It was found that an ironoxidizing strain of acidophilic microorganisms, Acidithiobacillus ferrivorans, is effective in the leaching of sulfide ores from the deposits in Russia's Murmansk region. Sulfide mineralization of the studied mineral feeds was described using the methods of Xray phase ...
