Recovery Of Microfine Poor Hematite Ultrafine Grinding Technology

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 and the
