Amongst the following, oxide ores are : calamine, fools's gold, cuprite zincite, chalcocite, haematite, bauxite, magnetite, cassiterite

Explanation

To determine which of the given ores are oxide ores, we need to analyze each ore and identify its chemical composition. Oxide ores are those that contain metal combined with oxygen.

1. **Calamine**: This is a zinc ore, and its chemical formula is ZnCO3 (zinc carbonate). It is not an oxide ore.

2. **Fool's Gold**: This is actually pyrite, which is an iron sulfide with the formula FeS2. It is not an oxide ore.

3. **Cuprite**: This is a copper oxide ore with the formula Cu2O. This is an oxide ore.

4. **Zincite**: This is a zinc oxide ore with the formula ZnO. This is an oxide ore.

5. **Chalcocite**: This is a copper sulfide ore with the formula Cu2S. It is not an oxide ore.

6. **Hematite**: This is an iron oxide ore with the formula Fe2O3. This is an oxide ore.

7. **Bauxite**: This is an aluminum ore, primarily composed of aluminum oxide (Al2O3·2H2O). This is an oxide ore.

8. **Magnetite**: This is an iron oxide ore with the formula Fe3O4. This is an oxide ore.

9. **Cassiterite**: This is a tin oxide ore with the formula SnO2. This is an oxide ore.

### Summary of Oxide Ores:
- Cuprite (Cu2O)
- Zincite (ZnO)
- Hematite (Fe2O3)
- Bauxite (Al2O3·2H2O)
- Magnetite (Fe3O4)
- Cassiterite (SnO2)

### Final Answer:
The oxide ores among the given options are: **Cuprite, Zincite, Hematite, Bauxite, Magnetite, and Cassiterite.**
