separation of silica from iron ore

Developments in the physiochemical separation of iron ore

01/01/2015· The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores. There are, however, other impurities in some deposits that also

Silica and Iron Recovery from a Residue of Iron Ore Flotation

The developed process of silica and iron recovery consisted of size classification, magnetic separation, and removal of impurities by leaching. A concentration of SiO2 from 33.4% to 67.0%, with 60.0% of mass reduction, was achieved by size classification. After magnetic separation, the SiO2 grade increased from 67.0% to 95.0%, in non-magnegtic fraction and iron increased from 40.1% to 60.2% in

Removal of Silica and Alumina as Impurities from Low

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

Role of silica and alumina content in the flotation of

10/03/2016· In reverse flotation, the removal of silica from iron ores is typically carried out by amine based collectors. Reagents such as dodecylamine, ether amines, ether monoamines, di-amines and quaternary ammonium salts are used in cationic flotation ( Ma et al., 2011, Vieira and Peres, 2007 ).
