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.
