Iron ore is a basic mineral that occurs in the form of beds and layers due to the deposition, accumulation, and concentration of layers of rocks. In India, iron ore is found in abundance. It is the backbone of industrial development because it's used for making machines. Before they are constructed with bricks and cement, iron is used to construct the framework of buildings.
