Nickel sulfide ore

Nickel sulfide ores associated with komatiites in Archean greenstone belts are the most important examples of mag- matic mineralization in volcanic rocks. They contain about 25 percent of the world total identified nickel resource in deposits with ≥0.8 percent Ni, as well as significant amounts of copper and platinum-group elements (PGE)

    The research results showed that cadmium, cobalt, copper, nickel, and zinc re-precipitate during the early stages of the heap leach process. A very low acid consumption was achieved on production scale (less than 1 kg of acid per tonne of ore) in comparison to previous studies (close to 40 kg of acid per tonne of ore)

All nickel ores have relatively low nickel content, the classification is as follows: high-grade nickel ore has Ni content greater than 1.8%, middle-grade nickel ore has Ni

    Nickel is most widely used in the production of stainless steel. Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity

    Nickel is commonly present in two principal ore types – sulfide or laterite ores. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt, and sometimes other precious metals such as gold or platinum and palladium (generally grouped as platinum group metals or PGMs)
