US4206878A - Beneficiation of iron ore - Google Patents
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 rejected and the concentrate passed to a flotation step, where a high iron content concentrate froth is made …
