READ MOREore dressing machines ore present in tailings dam Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
READ MORE· The method does not use water to process iron ore, instead it transforms mining tailings – with low iron content and no commercial value – into high iron content and low contaminants, making it economically viable. As iron ore must be composed of grades of at least 58 per cent, mining companies stack the lower grade material on tailings dumps.
