Roasting of a metallic sulfide MS in pure oxygen is carried out at a particular temperature where the probable stable solid phases are M, MS, MO and MSO4. In case the system attains equilibrium and thus satisfies phase rule, it is possible to obtain a combination of the following solid phases in the roasted product.
P. M, MS and MO
Q. M, MS, MO and MSO4
R. MSO4, MS and MO
S. MS and MO
