There are three main steps to the production of iron ore—mining, processing, and pelletizing. Mining is the process of taking iron ore from the earth; the processing is removing all the useless materials (gangue). Achieving a specific grade of chemical composition and pelletizing is turning the processed materials into a small, usable unit.
