The slag obtained during the extraction of copper from copper pyrites is composed mainly of
Options
- AC u 2 S
- BF e S i O 3
- CC u S i O 3
- DS i O 2
Correct answer
B. F e S i O 3
Step-by-step solution
The reactions are 2 C u 2 S + 3 O 2 → C u 2 O + 2 S O 2 C u 2 O + F e S → F e O + C u 2 S 2 F e S + 3 O 2 → 2 F e O + 2 S O 2 F e O + S i O 2 → F e S i O 3 (Impurity) (Flux) (Iron silicate slag)
