Nickel British Geological Survey

Nickelbearing lateritic ores, with average nickel content of 1–1.6%, are formed by tropical and subtropical surface weathering. Table 3 summarises these and other types of nickel deposit. Laterites currently account for around 70 per cent of nickel contained in landbased deposits but contribute only 40 per cent of world production.

Laterite geology Britannica

Laterite: Laterite, soil layer that is rich in iron oxide and derived from a wide variety of rocks weathering under strongly oxidizing and leaching conditions. It forms in tropical and subtropical regions where the climate is humid. Lateritic soils may contain clay minerals but they tend to be silicapoor,

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, countercurrent decantation and product

Where are the world's top nickel deposits loed?

Massive nickel demand from China's booming industries has resulted in an increase in Indonesian exports of unprocessed nickel laterite ore from 4 metric tons in 2006 to 41 metric tons in 2011. Over 50 percent of nickel laterite imports into China came from Indonesia.

FERRONICKEL PRODUCTION AND OPERATION Pyro

Nickel ores can be subdivided into two groups as sulphide ores and lateritic ores. Despite the fact that 70% of land based nickel ores are lateritic, 60% of primary production is from sulphide ores [1, 2, 4, 5]. The importance and use of lateritic ores are increasing due to the increase in nickel prices and decrease in the reserves of sulphide

Processing Nickel Laterite Ore without Pyrometallurgy

Nickel pig iron (NPI) is usually made with lower grade limonite ores while ferronickel (typically 8 to 12% Ni) is made with higher grade nickel laterite ores, often saprolites (lower iron content) or in the case of limonites by lowering the iron recovery.
