    Flash smelting - Wikipedia

    Flash smelting (Finnish: Liekkisulatus, literally "flame-smelting") 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.

    12.3 Primary Copper Smelting

    Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which ...

    The slurry is then cooled in a series of flash tanks to around 106°C at atmospheric pressure and by flashing off steam. This steam is used to preheat spent liquor. In some high temperature digestion refineries, higher quality bauxite (trihydrate) is injected into the flash train to boost production. This "sweetening " process also reduces the energy usage per tonne of production.
