In the batch flotation where a froth layer existed, kerosene behaved differently when used in conjunction with the three collectors. Kerosene helped improve the batch flotation when sodium oleate or oleoyl hydroxamic acid was used as a collector. However, it reduced concentrate weight yield, grade and

  • Mycobacterium phlei as a flotation collector for hematite

    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 point of zero charge of the microorganism. An excellent correlation between the flotation recovery and bacterial adhesion on hematite is observed. The adhesion of Mycobacterium phlei on hematite

  • Direct hematite flotation from an iron ore tailing using

    Hematite recovery was feasible at a pH of around 3. In microflotation tests, the iron grade and recovery reached approximately 37% and 30%, respectively. These values increased in batch flotation circuits, specifically in the cleaner stage, the iron grade reached approximately 44% and the recovery was approximately 65%. Thus, the current development proved that this particular treatment of ore

  • Flotation behavior of hematite fines flocculated with

    Separation of a hematite-quartz mixture can be achieved by SDS flotation of PAA-flocculated hematite. Maximum selectivity results with the addition of small quantities of PAA, while excess polymer is detrimental to the recovery of hematite. Consecutive flotation states on a single feed yield a higher grade hematite product at some expense to the overall recovery.
