    Iron Ore

    We have hands-on experience with all types of ore bodies and mineralogy. Our work covers the entire iron-ore value chain, from mining through to crushing, grinding, and beneficiation by gravity, magnetic, or heavy media separation. Next comes flotation and filtering, followed by downstream processing, such as pelletizing and sintering.
