Most sulfide ores have traditionally been processed using pyrometallurgical techniques to produce a matte for further... Electrorefining A second common form of further,nickel extract from ore - eurlberguin.fr,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.A New Process for Cobalt Nickel Separation,For laterite ores, these are the main routes used in the hydrometallurgical nickel processes. One notable exception in recent times was the Bulong project, which succeeded in achieving . A New Process for Co-Ni Separation – ALTA 2010 3 excellent cobalt-nickel separation primary leach liquor by Cyanex 272.
