Step-by-step solution

Haematite is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 2+ Fe 3+ 2 O 4 ( Fe 3 O 4 ). Calamine is an ore of zinc. It is zinc carbonate( ZnCO 3 ). Kaolinite is a clay mineral, with the chemical composition Al 2 ( OH ) 4 Si 2 O 5 . It is an important industrial mineral.
