news iron ore hematite separation

Developments in the physical separation of iron ore

The ore is mainly composed of magnetite, hematite, martite, and quartz. It is very difficult to produce a high quality iron ore concentrate by magnetic separation alone for this type of iron ore. The ore is first ground using ball mills down to about 90% 75 m.

Removal of Silica and Alumina as Impurities from Low Grade

This 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 density of
