Slags in ferroalloys production—review of present knowledge
tively, ferrochrome and ferromanganese (containing silicon and carbon) as well as associated slags by the use of a suitable carbonaceous reductant (coke, anthracite, char). The slag is created in the process from gangue material associated with the ores as well as from fluxes added to the burden. The fluxes are added to assist in the smelting by affecting the activities of .

plant for recovery of metal from ferrochrome slags
Ferrochrome smelting slag processing line is mainly to recover the valuable ferrochrome alloys from the slag in a forms that will be as far as possible directly saleable. This production line is now producing saleable ferrochrome containing less than 2% slag at a recovery of over 96% of liberated metal.

reactants required for chromium recovery into account. According to the results, at least 30% of ferrochrome production slags are required in the mixtures in order to avoid the formation of dicalcium silie, whereas the excessive use of ferrochrome slags increases the amount of solid spinel phase in the system thus making the chromium recovery more challenging. 1. .
