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 …
Nickel is recovered as a by-product of the platinum-producing process operated by Anglo Platinum. The metal is mined mainly as sulphide minerals contained in platinum ores. These pass through the concentrating, smelting and converting process route and nickel is finally recovered by electrowinning.

Sulphide Pyrometallurgy – Smelting • Production: − 90+% of sulphide processing − 40% of world nickel production • Process: − Beneficiation − Roasting − Smelting − Refining – not our focus today Pros Problems Sulphide oxidation is exothermic SO 2 production Widely known and understood Arsenic emissions Suitable ores running out
Sep 24, 2020· A basic principle for determining the flotation process is that it is better to allow copper to enter the nickel concentrate, and to avoid nickel entering the copper concentrate as much as possible. Because the nickel in the copper concentrate is lost during the smelting process, the copper in the nickel concentrate can be completely recovered.
