Flotation of low grade iron ore

At the Huasco Pellet Plant of Compaa de Aceros del Pacfico, Chile, the production of iron concentrate suitable for pellet feed from a low-grade iron ore was technically evaluated. In this study, three treating schemes including comminution, magnetic concentration and flotation in pneumatic cells were tested. The best results were obtained at the laboratory scale by flotation technique using

    Flotation applied to iron ores with complex mineralogy

    A low-grade iron ore from one of the largest Mexican deposits was investigated. Flotation was performed on samples with different particle size distribution to verify the influence of liberation and evaluate iron losses in case of a possible screening prior flotation. The results show that there is a considerable difference in the quality of the final product from flotation between the samples

    Froth Flotation of Iron Ores

    Jan 02, 2012 With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore

    Hematite Processing by Flotation

    Apr 19, 2016 Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores. Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with “Sub-A” Flotation to produce concentrates that average

  • Optimization of Reverse Cationic Flotation of Low-Grade

    Optimization of Reverse Cationic Flotation of Low-Grade

    Sep 19, 2017 Due to gradual depletion of high-grade iron ores, there is a need to investigate the treatment of low-grade iron ores. Current procedures are time and cost intensive. Batch laboratory scale reverse cationic flotation was employed to concentrate low-grade Fe ore, found in fluorspar tails in the form of hematite. This study used two types of depressants (soluble starch and dextrin) and two types

    May 12, 2021 Iron ore flotation is a key technique to concentrate intermediate-low-grade ore, in order to reach the market requirements for higher-grade concentrates of iron. The presence of some impurities in addition to quartz in iron ore, aluminium silicates, and minerals containing phosphorus impair productivity in the steel industry and have an impact

    Nov 01, 1995 The recovery of iron from low-grade (31.6% Fe) Muro iron ore was investigated using reverse anionic flotation of quartz. Tests were performed to investigate the effect of pH, the effects of using distilled vs. tap water as the flotation medium and the effects of using cassava starch vs. dextrin for the depression of iron minerals.The optimum results were obtained around pH 10 and 11, and
