• Mycobacterium phlei as a flotation collector for

    Mycobacterium phlei has very good potential as a hematite flotation collector The flotation recovery of hematite is dependent upon the solution pH and concentration of the microorganism The critical pH for maximum recovery of hematite is around three, which corresponds to the

    these findings Thus it has been shown that the hematite flotation using oleate as collector is highly sensitive to pH [10] and that the best flotation recoveries are obtained in the pH range of 68 [1,38,1012] Also, increase in the conditioning temperature has been reported to significantly improve the hematite flotation response [5]

  • Effect of particle size on flotation performance of hematite

    anionic flotation were described by Araújo et al (2005) In China, anionic flotation is often employed according to iron ore characteristic and technological conditions (Chen and Zhang, 2013) For direct flotation, hematite can be floated with fatty acid as collector

    The flotation response of both quartz and hematite with cationic and anionic collectors in isolation and with mixed cationic / anionic collector systems was evaluated as well

  • Adsorption mechanism of mixed collector systems on

    The flotation response of hematite as a function of pH at fixed cationic and anionic collector concentration is shown in Fig 1Results clearly indicate that with cationic C 12 amine collector the flotation recovery increases with the increase of pH till around pH 95 and thereafter, the recovery decreases marginally A maximum recovery, with C 12 amine, of about 60% is attained at pH 95
