Read the source given below and answer the question that follows:

Iron ore and mangoes are two important ferrous minerals mined in India. The two main ores of iron are magnetite and hematite. Magnetite has up to 70% iron, while hematite has 50-60% iron. Karnataka and Orissa are the main iron ore producing states in India, followed by Chhattisgarh, Goa and Jharkhand. Major iron ore producing belts of India are: the Orissa Jharkhand belt, the Durg-Bastar-Chandrapur belt, the Bellary-Chitradurga-Chikmagalur-Tumkur belt and the Maharashtra-Goa belt.

High-grade hematite is mined in the Badampahar mines in Mayurbhanj and Kendujhar districts of Orissa. The Durg-Bastar-Chandrapur belt is spread over parts of Chhattisgarh and Maharashtra. These hills contain 14 deposits of hematite.

The Bellary-Chitradurga-Chikmagalur-Tumkur belt lies in Karnataka. The Kudermukh mines in this region hold one of the largest deposits of iron ore in the world. Orissa is the main manganese-producing state in India, followed by Madhya Pradesh and Karnataka.

The Maharashtra-Goa belt is spread over parts of Goa and the Ratnagiri district of Maharashtra. Steel is a mixture of several minerals besides iron ore, and one such important mineral is manganese. The reserves of non-ferrous minerals in India are not as abundant as those of ferrous minerals. Copper and bauxite are two important non-ferrous minerals mined in India. Copper is widely used in the electrical, electronic and chemical industries.

Detailed Solution

Copper and Bauxite are two non-ferrous minerals in India.
Non-ferrous minerals are metals and alloys that do not include significant iron concentrations. Non-ferrous metals are utilised because of advantageous features such as reduced weight, greater conductivity, non-magnetic properties, or corrosion resistance, such as Zinc. They are often more expensive than ferrous metals. In the iron and steel industries, non-ferrous materials are also used. Bauxite, for example, is utilised as a flux in blast furnaces. Non-Ferrous mineral reserves in India are not as abundant as ferrous mineral reserves. Copper and Bauxite are two of India's most important non-ferrous minerals.
