Nickel. Nickel and cobalt are predominantly produced via the beneficiation and pyrometallurgical processing of nickel sulphide ores, and hydrometallurgical processing of nickel laterite ores. Nickel is recovered either as ferronickel (FeNi) from saprolite ores or as an intermediate mixed sulphide/hydroxide from limonite ores.
