The question asks to identify which mineral listed is a copper ore. An ore is a rock or mineral that contains enough valuable metal to be mined profitably.
Mineral Analysis
Let's examine the options:
- Chromite: This is the primary ore of chromium, not copper. Its chemical formula is approximately FeCr2O4.
- Malachite: This is a well-known copper ore. It is a copper carbonate hydroxide mineral, with the formula Cu2(CO3)(OH)2.
- Haematite: This is the primary ore of iron, not copper. Its chemical formula is Fe2O3.
- Magnetite: This is also a primary ore of iron, known for its magnetic properties. Its chemical formula is Fe3O4.
Conclusion
Based on the analysis, Malachite is the only copper ore among the given options.
