Removal of Silica and Alumina as Impurities from Low Grade

May 03, 2018This study investigates the removal of silica and alumina as impurities from hematite based low grade iron ore containing 34.18 mass% iron, 31.10 mass% of silica and 7.65 mass% alumina. Wet high intensity magnetic separation (WHIMS) and reverse flotation (RF) were investigated. In WHIMS process, 93.08% of iron was recovered with a grade of 53.22 mass% at an optimum magnetic

Coal Washing, Magnetic Separation Processing

Discover Magnetite Processing. The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe3O4) which when processed produces a magnetite concentrate with a magnetic content in excess of 96% magnetics. Further magnetic separation and milling produces even higher iron levels in the magnetite concentrate.
