Manganese is mainly used in the manufacturing of Steel. The Iron and steel industries are the basic industry as rest all other industries are dependent on them. Steel is used in the manufacturing of goods, construction material, defence medical, telephonic, scientific and variety of other goods. An Integrated plant is one that is huge and manufactures everything from getting raw materials to produce the final product whereas mini Steel plants are smaller, have electric furnaces. They produce mild and alloy steel. The problems associated with Steel Industry are : 1. Coking coal has limited availability and is costly. 2. The labour has lower productivity. 3. The industry requires huge energy supply, which is not always available. 4. Poor Infrastructure. The developments that have led to a rise in the production capacity are: 1. Liberalization and Foreign direct investments have given a stimulus to the industry. 2. Earlier only public enterprises would participate in the industry, but now private entrepreneurs have also plunged into it. 3. As steel products are needed in every other sector too, its demand has increased.
