4.3 Roasting of Copper Concentrate. One of the drawbacks of matte smelting is the production of large quantities of SO 2 that must be disposed of. One way to avoid this is to roast copper concentrate in the presence of lime or limestone, which captures the sulfur as CaS or CaSO 4. The aim is to produce metallic copper as one of the products ...

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. A second flash smelting system was developed by the International Nickel Company ('INCO') and has a different concentrate feed design compared to the Outokumpu ...
Process for producing raw copper continuously in one stage from sulfidic copper concentrates and ores containing impurities such as lead, antimony, bismuth and arsenic, by feeding finely-divided copper concentrate and ore and oxygen or oxygen-enriched air into the upper part of the reaction zone to produce a suspension in the reaction zone, the suspension being fed, at a high temperature ...
