Mar 10, 2016 · In contrast, in silica bearing iron ore, the quartz particles are coarser in size and less prone to be coated on iron minerals. In fact there are a number of investigations based on reverse flotation techniques for the separation of quartz particles from hematite fines ( Montes-Sotomayor et al., 1998 , Uwadiale, 1992 , Yuhua and Jianwei, 2005 )… Read more

Mar 19, 2017 · Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice. This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500 …… Read more

silica and iron recovery froma residue ofiron oreflotation

A study of silica and iron recovery from the iron ore concentration tailing is presented. The residue is composed of 40.1% Fe, 33.4% SiO2, 8.31% Al2O3, 0.08% P, and 0.34% MnO. 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… Read more
