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
A. P or Q
B. P or, Q or, R
C. Q or, R or, S
D. P or, R or, S
