Smelting an overview ScienceDirect Topics

Smelting is a form of extractive metallurgy to produce a metal from its ore. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gasses or slag and leaving just the metal behind. The reducing agent is commonly a source of carbon such as coke, charcoal, and coal. The modern SR technologies aim at direct use of noncoking coal

There are two commercial classes of nickel ore, the sulfide ores (pentlandite and pyrrhotite) and silicate-oxide. Most nickel is produced from the sulfide ores, and the two largest producers, Canada and the Russian Federation, account for 20–25% each of total annual production, which was 784.82 thousand tones in 1988.
