Difference between Roasting and Calcination Major Roasting metallurgy chemeurope

Roasting is the process in which the ore is heated below its melting point in presence of air to oxidise the impuriti eg carbon sulphur etc removed as their gaseous oxid Calcination is the process of heating the ore below its melting point an absence of air to remove volatile impurities like arsenic etcRoasting 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
