Correct Answer: 3
Solution and Explanation
To determine how many of the given minerals are sulphide-based, we need to analyze each mineral: (a) Baryte, (b) Galena, (c) Zinc blende, and (d) Copper pyrites.
- Baryte (BaSO4): It's a sulfate mineral, not a sulfide.
- Galena (PbS): This is a sulfide mineral.
- Zinc blende (ZnS): This is a sulfide mineral.
- Copper pyrites (CuFeS2): This is also a sulfide mineral.
