Roasting_(metallurgy) - chemeurope

Roasting is a metallurgical process in which sulfide ores are converted to oxides, prior to smelting.It differs from calcination in that in calcining limestone or other carbonate ores, the chemical change is achieved merely by the application of heat, whereas roasting involves a reaction between a gas and the solid ore: . MS n + 1.5nO 2 → MO n + nSO 2.
