CN102268537A, The invention discloses a method for extracting cobalt and nickel from laterite-nickel ore, which comprises the following steps of: performing roasting preprocessing on the laterite-nickel ore; blending the roasted material with water to obtain pulp; directly adding ion ...process of extracting ore inn nickel, NiCo Laterites A Deposit Model USGS Dalvi and others, 2004). Recently, an oreprocessing technique was developed to treat the entire laterite profile. This innovation, DNi, developed by Direct Nickel, is a hydrometallurgical process capable of extracting 95 percent ...Nickel: smelting, producing, 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.CN104726724A, The invention provides a method for extracting scandium from nickel laterite ores. The method includes carrying out leaching treatment on the nickel laterite ores by the aid of sulfuric acid to obtain leach liquor of the nickel laterite ores; carrying out scandium-rich ...Lateritic nickel ore deposits, Lateritic nickel ore deposits are surficial, weathered rinds formed on ultramafic rocks. They account for 73% of the continental world nickel resources and will be in the future the dominant source for the mining of nickel..
