Detailed Solution

1)      Hematite: It is a mineral of iron. It is a dark red stone from which we get iron. It has a red or earthy-coloured tone with a hearty shine and is a heavy, typically hard oxide mineral that comprises the primary iron metal.
2)      Bauxite: It is a stone composed of aluminium oxides. It is a fundamental metallic mineral that is light and impervious to consumption. It joins the strength of the metals like iron. Odisha is the primary state delivering bauxite. Moreover, Koraput and Sambalpur are a few significant locales where bauxite is found.
3)      Coal: It is utilised for the creation of power for both homegrown and business utilisation. Anthracite is the best kind of coal. Lignite is low-quality coal with high dampness content. Bituminous coal has been exposed to high temperatures while being shaped. It is a richly tracked-down petroleum derivative.
4)      Limestone: It is composed of calcium and magnesium carbonates. It shapes the essential unrefined substance for the concrete business. Limestone is likewise utilised for purifying iron metal in the impact heater.
