Solution

Haematite is the anhydrous ferric oxide

F e_{2} O_{3}

, the chief ore from which iron is smelted. Bauxite is the hydrated aluminium oxide

A l_{2} O_{3} \cdot x H_{2} O

, the ore leached in the Bayer process. Magnetite is the magnetic mixed oxide

F e_{3} O_{4}

, which holds iron in both the

+ 2

and the

+ 3

state. Malachite is the green basic copper carbonate

CuC O_{3} \cdot Cu (OH)_{2}
