STATEMENT-1: Extraction of zinc from sphalerite ore involves the roasting follow
STATEMENT-1: Extraction of zinc from sphalerite ore involves the roasting followed by reduction with coke. STATEMENT-2:Zinc can be commercially extracted by hydrometallurgy.
- A. STATEMENT-1 is True, STATEMENT-2 is True: STATEMENT-2 is a correct explanation for STATEMENT-
- B. STATEMENT-1 is True, STATEMENT-2 is True: STATEMENT-2 is NOT a correct explanation for STATEMENT-1
- C. STATEMENT-1 is True, STATEMENT-2 is False
- D. STATEMENT-1 is False, STATEMENT-2 is True
Step-by-step solution
Statement-1 correctly describes the pyrometallurgical extraction of zinc from sphalerite: roasting (ZnS to ZnO) followed by carbon reduction. Statement-2 is also true because zinc is commercially extracted by hydrometallurgy (leaching + electrowinning). However, hydrometallurgy is an alternative process, not an explanation for the described pyrometallurgical route, so Statement-2 does not explain Statement-1.
