Ausmelt Smelting And Converting


Copper - Sulphuric Acid

Flash converting closely resembles flash smelting. Flash smelting is a closed process and, consequently, off-gas emissions can be efficiently controlled. Flash converting had its first application in the expansion and modernization of Kennecott's copper smelter near Salt Lake City, Utah, which was implemented during 1992-95.
