Steps in iron ore beneficiation

Beneficiation of iron ore. United States Patent 4206878. Abstract: Iron ore is beneficiated using separation steps based on mineral composition without the use of separation steps based entirely on size. In a preferred sequence of steps the iron ore is passed from a ball mill through a magnetic separator where low iron content tailings are
