Nickel
Nickel is mainly used to make stainless steel: it adds strength and corrosion resistance to the steel. With its ability to handle high temperatures, nickel features in specialty steels and superalloys found in jet engines, as an example. Nickel compounds are used in batteries – increasingly so in the electric vehicles helping facilitate our ...
Fluxing Optimisation and Control Improvements at the Kalgoorlie Nickel
The primary function of flash smelting is upgrading sulphide concentrate through oxidation then removal of impurities (primarily FeO, SO 2 and MgO) by separation of the slag and gas phases from the enriched sulphide stream (nickel matte) at temperatures in excess of 1300 °C. Flux must be added to allow the formation of a …

The general process flowsheet of the copper smelter used for piloting the COCOP solution is pre-sented in the figure 1. The main raw materials are sulfidic copper concentrates that are first blended to feed mixture and then dried before processing. Flash Smelting Furnace (FSF) and Peirce-Smith Converters (PSC) are in the heart of the operation.
THE ALLOY THAT TIME FORGOT
Mining and smelting Early on, ore was separated into "a mixed copper-nickel ore, copper pyrites, pyrrhotite and diorite rock," with nickel content 1.28-8.12% and copper 0.49%-15.71% between 1892-991. It was at Creighton, mined from 1901, that pyrrhotite with a 2.3:1 nickel copper ratio was discovered and became synonymous with Monel's
