    The Caron Process :: Total Materia Article

    In general, nickel can be extracted from its ores using smelting, high pressure acid leaching HPAL and Caron roast/leach processes. The Caron process, which involves reduction roasting of the ore followed by ammonia leaching of reduced ore, is one of the ways in which nickel laterite can be treated.

    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.
