Roasting of metallic sulfides have been studies by a large number of investigators in recent years. Wadsworth, McCabe in U.S.A. and Smirnov and his group have contrib-uted to our understanding of the roasting mechanism to a very considerable extent. On the basis of these works, two kinds of mechanisms have been proposed for the formation of metallic sulfate from metallic sulfide and oxygen. One of the theory suggests a direct formation of metallic sulfate, whereas the other theory assumes prior formation of metallic oxide of SO2 to SO3, which combines with metallic oxide to give sulfate. Present investigation is aimed at further clearing up the mechanism of sulfate formation and estabilishing the role of individuality of the system on a more generalised basis.
