Reductant Selection In Ferro-Alloy Production: The Case For The Importance Of Dissolution In The Metal
Organization: The Southern African Institute of Mining and Metallurgy
Jan 1, 2002
The typical reactions which the reductants undergo during ferroalloy production are reviewed, and identified as reaction with CO2 and with SiO, and dissolution in metal. Available reactivity tests for these three reactions are reviewed. It is proposed that it is worthwhile considering dissolution kinetics as a reactivity parameter. Greater crystallinity of the reductant decreases CO2 and SiO reactivity, but increases dissolution rates.
