The price of laterite ore with 1.5% nickel content has risen on reduced supply during the Philippines' rainy season and robust demand from Chinese nickel pig iron (NPI) producers amid thin trading, Metal Bulletin learnt on Tuesday November 22.
Laterites are a source of aluminium ore; the ore exists largely in clay minerals and the hydroxides, gibbsite, boehmite, and diaspore, which resembles the composition of bauxite. In Northern Ireland they once provided a major source of iron and aluminium ores. Laterite ores also were the early major source of nickel

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.
studies involved the optimization of nitric acid leaching of nickel laterite ores at atmospheric pressure for high nickel and cobalt extraction. The main parameters optimized after the characterization of laterites were the nitric acid concentration, leaching temperature, duration of leaching and the particle size of the ore …
Below the nickel limonite another type of nickel ore has formed in many deposits. This is called nickel silicate ore which consists predominantly of partially weathered serpentine. It is depleted in magnesium and forms with 1.5 – 2.5 % Ni the most relevant type of lateritic nickel ores.
