Detailed Solution

1)      Metallic minerals having iron content are known as ferrous minerals. These minerals make up three-fourths of the total value of the production of metallic minerals and are also a strong basis for the development of metallurgical industries.
2)      Non-ferrous minerals do not contain iron. Bauxite is a non-ferrous mineral.
3)      Potash is a non-metallic mineral that occurs in the form of beds or layers due to the deposition and concentration of horizontal layers. These are formed due to evaporation in arid regions.
4)      Uranium is used for generating nuclear power to produce electricity. Nuclear or atomic energy is a non-conventional source of energy.
