Ores of nickel

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, with many recognizing nickel laterite ores as the future of the

    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 content between 1.3-1.7%, low-grade nickel ore has Ni content between 0.6-1.2%. Nickel is continuously mined, even at these low percentages of ores, because it is in high

    There were no active nickel mines in the United States in 2011, although small amounts of nickel were recovered as a byproduct from processing copper and palladium-platinum ores. Several deposits in Minnesota and Michigan have potential for development.. Recycled nickel is an extremely important source of supply. In 2011, recycled nickel accounted for approximately 43 percent of U.S. nickel
