suitable concentration of hematite for froth flotation

two main features of hematite-oleate flotation system. These are: (1 Hematite flotation response is very sensitive to pH especially in the neutral pH range and the maximum floatability is observed close to pH 8.0 with 3 X 10-5 mole/liter total oleate concentration. (2) For a given hematite sample the pH of maximum 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 better than 62% Fe with less than 9% SiO2 and with a high recovery

    Aug 01, 2019 1. Introduction. With the over-depletion of high-grade iron (Fe) ore deposits, froth flotation has become the most important mineral separation technique in processing of medium-grade and low-grade iron ores (Rocha et al., 2010, Quast, 2017, de Medeiros and Baltar, 2018, Kumar et al., 2018).Medium-grade and low-grade iron ores are commonly complex mineralogical compositions where valuable
