The main key facilitators produced by the process include controlled oxidation of Fe and S a large evolution of heat and the effective melting of solids.

70 Years Of Flash Smelting Shaping The Industry Metso

Jun 11 2019 70 years of flash smelting - shaping the industry. This year marks the 70th anniversary of flash smelting. The technology was operated for the first time on an industrial scale on April 20th 1949 at the Harjavalta copper smelter in Finland. The go-ahead for construction of the pilot plant at Harjavalta was given in 1946 and the first experiments were undertaken in February 1947.

Production Enhancement And Operation

Flash smelting process developed by Outokumpu is considered to be one of the most important innovations in copper metallurgy in the 20 century. In flash smelting process the concentrate along with recycled dust flux is fed into the vertical reaction shaft from the CJD burner where the oxygen-enriched air is injected too. In the
