Which is correct about Magnetite iron ore? (a) Magnetite is the most important industrial iron ore in terms of the quantity used. (b) Magnetite has the inferior magnetic qualities which is not valuable in the electric industry. (c) It is the finest iron ore with a very high content of iron up to 70%.
Bauxite is the most common aluminium ore. Bauxite occurs as a weathered cover or blanket, known as laterite or duricrust, over a variety of alumina-bearing rocks. It forms when large amounts of rainfall leach away the more mobile elements in the host rock leaving the relatively immobile aluminium with some silicon, iron and titanium.

Physical Properties of Bauxite. Bauxite is typically a soft material with a hardness of only 1 to 3 on the Mohs scale.It is white to gray to reddish brown with a pisolitic structure, earthy luster and a low specific gravity of between 2.0 and 2.5. These properties are useful for identifying bauxite; however, they have nothing to do with bauxite's value or usefulness.
