Selective Reduction of Laterite Nickel Ore

Most laterite nickel ore processing is carried out using Elkem process. The Elkem process uses Rotary Kiln and Electric Furnace (RKEF) to reduce and smelt laterite nickel ore. Commercialization of Elkem process itself began with the development of a pilot plant in 1953­1954. At that time, the Elkem process was used to process garnieritic nickel ore

Salinity in Nickel Laterite Processing - SGS

The effect of salinity on the processing of various nickel laterite ores is discussed. In particular, the presence of high concentration chloride, sulphate, sodium, calcium and magnesium is addressed. Key unit process operations affected by these ions include ore preparation, pressure acid leaching, counter-current decantation and product purification and precipitation. Some of the process implications of these dissolved species are discussed in terms of rheology and process
