Solution

Haematite is a common iron oxide compound with the formula,Fe2O3 and is widely found in rocks and soils.

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe2+Fe3+2O4(Fe3O4).

Calamine is an ore of zinc. It is zinc carbonate(ZnCO3).

Kaolinite is a clay mineral, with the chemical composition Al2(OH)4Si2O5. It is an important industrial mineral.

Hence, the correct answer is option: 'A'.
