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

Beneficiation of Indian High Alumina Iron Ore Fines a Case

Jan 02, 2012 The iron ore fines sample was collected from the spiral classifier overflow of a typical Iron ore beneficiation plant of Noamundi, India. The sample was dried, thoroughly mixed and analysis indicated that the dried sample contained 59.77% of total iron, 5.89% alumina and 4.71% silica with an LOI (Loss on Ignition) of 5.53%.

Role of silica and alumina content in the flotation of

Mar 10, 2016 It is believed that beneficiation of iron values by flotation coupled with agglomeration such as pellet making will be emphasized more in future. Iron ores can be concentrated either by direct anionic flotation of iron oxides or reverse cationic flotation of silica. In direct flotation, oleic acid or its sodium salt is the preferred reagent.
