Flash smelting. Flash smelting (Finnish: Liekkisulatus) is a smelting process for sulfur-containing ores including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. It has also been adapted for nickel and lead production.

The making of nickel is a process which involves a number of steps: 1. Mining. Nickel mined from lateritic ore is mined from various depths beneath the surface using large earth-moving equipment. The other nickel containing type of ore, sulfidic ore, is usually found in combination with copper ore and is mined underground.

Processing. After mining, nickel ores are further processed to upgrade their nickel contents from 1-4% typical of the ores to concentrates with grades in the range 10-20%. Concentration involves crushing the ore and separating nickel-bearing from other minerals using various physical and chemical processing methods.

Nickel mining in Indonesia
History. Nickel ore was first prospected in Indonesia (then known as Dutch East Indies) in 1901 in the Verbeek Mountains of Sulawesi by a Dutch mineralogist, with further discoveries in what is today Kolaka Regency in 1909. A Canadian geologist from Inco further prospected the existing deposits and in 1934 exploration efforts from a Dutch mining firm began.
