Therefore 80% above iron minerals need magnetic separation. Manganese minerals such as psilomelane, pyrolusite, and Rhodochrosite also have weak magnetic properties and are usually recovered by magnetic separation. Ilmenite, Wolframite, Monazite, and niobium-tantalite are all weakly magnetic minerals. Also used magnetic …
