On the basis of their composition ,minerals can be classified into metallic and non-metallic minerals.

Metallic mineral content metals in raw form . Iron ore, bauxite and manganese are metallic minerals. These are found as ores in the form of lodes or veins in igneous and metamorphic rocks. Metallic mineral may be ferrous and non- ferrous. The Ferrous minerals contain iron like elements such as manganese and chromites.
