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.
Flash Smelting - an overview | ScienceDirect Topics
网页2012年4月23日 · Flash smelting entails continuously blowing oxygen, air, dried particulate sulfide concentrate and silica flux into a 1300 °C furnace. The principal objective of flash smelting is to produce molten matte that is richer in Ni (and other metals) than the original concentrate.
网页Our proven Flash Smelting technology is the cleanest and most eficient smelting method for the production of copper and nickel from sulfide concentrates. Suitable for both new and existing smelter operations, it guarantees superior performance and output while helping producers comply with ever more stringent environmental regulations.

Flash Smelting Process - an overview | ScienceDirect Topics
网页2011年2月3日 · The flash smelting process is important in the production of nonferrous metals from sulfide minerals. In this process, fine, dried mineral particles and fluxes are injected into the furnace with industrial oxygen or oxygen-enriched air. The sulfide particles are ignited and burn in the turbulent gas jet.
