Maharashtra. Though, the ores are not of very high quality, yet they are efficiently exploited. Iron ore is exported through Marmagao port. Manganese Manganese is mainly used in the manufacturing of steel and ferro-manganese alloy. Nearly 10 kg of manganese is required to manufacture one tonne of steel. It is also used in manufacturing bleaching powder, insecticides and paints. Andhra Others Pradesh 2% 10% Fig. 5.2: Iron ore mine Karnataka The major iron ore belts in India are: 12% Odisha-Jharkhand belt: In Odisha high Madhya Pradesh grade hematite ore is found in Badampahar 33% mines in the Mayurbhanj and Kendujhar districts. In the adjoining Singbhum Odisha district of Jharkhand haematite iron ore is 16% mined in Gua and Noamundi. Durg-Bastar-Chandrapur belt lies in Chhattisgarh and Maharashtra. Very high grade hematites are found in the famous Maharashtra Bailadila range of hills in the Bastar district 27% of Chhattisgarh. The range of hills Fig. 5.3: Production of Manganese showing comprise of 14 deposits of super high state-wise share in per cent, 2018–19 grade hematite iron ore. It has the best physical properties needed for steel Dig a little deeper: Superimpose the maps making. Iron ore from these mines is showing distribution of iron ore, manganese, exported to Japan and South Korea via coal and iron and steel industry. Do you see Vishakhapatnam port. any correlation. Why? Ballari-Chitradurga-Chikkamagaluru- Tumakuru belt in Karnataka has large reserves of iron ore. The Kudremukh mines Non-Ferrous Minerals located in the Western Ghats of Karnataka India’s reserves and production of non- are a 100 per cent export unit. Kudremukh ferrous minerals is not very satisfactory. deposits are known to be one of the largest However, these minerals, which include in the world. The ore is transported as copper, bauxite, lead, zinc and gold play a slurry through a pipeline to a port near vital role in a number of metallurgical, Mangaluru. engineering and electrical industries. Let us Maharashtra-Goa belt includes the state study the distribution of copper and of Goa and Ratnagiri district of bauxite. MINERALS AND ENERGY RESOURCES 45 Reprint 2024-25
