C) sulphur has less affinity for oxygen at high temperatun
D) copper has less affinity for oxygen than sulphur at high temperature
Correct Answer: D
Solution :
[d] \[2CuFe{{S}_{2}}+{{O}_{2}}\to C{{u}_{2}}S+2FeS+S{{O}_{2}}\] (Copper pyrite) \[FeS+\frac{3}{2}{{O}_{2}}\to FeO+S{{O}_{2}}\uparrow \] \[FeO+Si{{O}_{2}}\to FeSi{{O}_{3}}\] (Remain \[C{{u}_{2}}S\] is called matte)You need to login to perform this action.
