Flash smelting Wikipedia
网页Flash smelting ( Finnish: Liekkisulatus, literally "flame-smelting") is a smelting process for sulfur -containing ores [1] including chalcopyrite. The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. [2] [3] It has also been adapted for nickel and lead production.
