Jan 01, 2011 The iron ore slimes were in situ sieved and analysed with 94.4% present as 25 microns particles. The sub-25 micron fraction contained 58.8% Fe, 5.74% SiO 2, 6.65% Al 2 O 3 and 0.15% P. The bulk mineralogical analysis of iron ore rejects slime is shown in Table 1 which contained about 13% silica and alumina gangue minerals. It was used as ...
The ore contains high alumina and silica and it is to be used as feed in steelmaking; however these impurities adversely affect the production of pig iron and steel [ 3]. High silica and alumina also form high viscous slag with greater volume in blast furnaces which requires more flux [ 4].

Jan 01, 2015 In 20–40 years' time, all the world's quality iron ore will be gone, and only low-grade ore will be left for processing , so more efficient and economic beneficiation techniques will be necessary. Commercial iron ore flotation systems have concentrated on the removal of quartz (silica) as the steel industry requires feedstock that is 2% SiO 2 ( Ma et al., 2013 ).
This article discusses the effect of physical and chemical modifications of starches on the anionic and cationic flotation of silica from oxidized iron ores and magnetite-taconite concentrates, and the results of the interaction of starch, pH, and calcium ions on the flocculation, clarification, and filtration of iron ore slimes and magnetite-taconite tailings.
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 …
