08-05-2020· The Lion smelter uses 37% less electricity than conventional ferrochrome processes to produce the equivalent volume of ferrochrome. In addition, the smelter needs far less coke than conventional...
Production Process. Ferrochrome (FeCr) is a corrosion-resistant alloy of chrome and iron containing between 50% and 70% chrome. Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures. Cr Ore, an oxide of chromium and iron, is reduced by coal and coke to form the iron-chromium alloy.
08-03-2017· The Lion ferrochrome smelter, owned and operated by the Glencore-Merafe Chrome Venture, uses 37% less electricity and considerably less coke than conventional ferrochrome processes to produce the equivalent volume of ferrochrome. In addition, the smelter uses significant amounts of locally produced, lower-cost anthracite and char.

13-01-2020· For example, ferrosilicon and ferromanganese are being produced with SAF type processes. Concerning the modelling of these processes, it is necessary - as it is in the production of ferrochrome - to know the influence of the electric current on the physical and chemical properties and phenomena within the furnace.
Premus process, Xstrata's proprietary technology in use at the Lion Ferrochrome plant in South Africa, is the most sophisticated, competitive and technological advanced process available for the production of ferrochrome from chromite ore (Xstrata, 2012). The technology involves three stages: sintering, pre-reduction, and smelting. Energy
