Nickel Laterite’s Integral Role in the Coming Nickel Boom

Nickel laterite ore processing depends on the zone from which the ore is mined As outlined earlier, each zone within a laterite deposit is very different in its chemical composition and, therefore, restricts the processing technique that can be used to extract the nickel.

Nickel: smelting, producing-Metalpedia

Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity In many stainless steel applications, 75% pure nickel can be used without further purification, depending on.
