The Aluminothermic Plant will see ACF processing about 300 tonnes of ultra low carbon high grade ferrochrome per month, with production set to reach 600 tonnes monthly at its peak.
The carbothermic reduction of chromite ore to produce high carbon ferrochromium is among the most energy intensive metal extraction processes performed, due not only to the highly endothermic nature of the reduction reactions but also the very high operating temperatures required for the smelting operation to separate the chrome-containing alloy from the discard slag.
The present invention relates to a process for producing low-carbon ferrochromium, Introducing scrap iron or ferrochrome into an electric furnace to produce a molten metal; Mixing molten chrome ore powder with a reducing agent powder containing no carbon to produce molten ferrochrome melted by a thermite reaction; And removing the slag produced by the thermite reaction.

of carbon free alloys has generated considerable interest in aluminothermic reduction of various .oxides. A common example of aluminothermic reduction is the thermit welding of rails and repair of steel castings. As early as in 1898, Goldschmidt (1) demonstrated the use of aluminium as a reducing agent in the production of refractory metals.
The commercial development of the aluminothermic process was due largely to the work of H. Goldchmidt. The reaction is generally highly exothermic and the risk of explosion, therefore, sometimes considerable. Gold Schmidt developed satisfactory techniques for its control on a production basis.
