  • Flotation separation of smithsonite from calcite using a

    Selective separation of smithsonite from gangue, especially calcite, remains a difficult problem in practice due to the fact that selectivity of depressants currently used is not good. In this study, fenugreek gum (FGM) was used as a new depressant to separate smithsonite from calcite when using cationic collector octadecylamine acetate (ODA).

  • Selective Flotation of Dolomite From Francolite Using

    It was reported earlier that francolite and dolomite from south Florida deposits cannot be selectively floated using conventional conditioning with sodium oleate as the collector. However, dolomite could be separated from francolite if the minerals were first conditioned at pH 10 followed by reconditioning at a lower pH. An optimum separation was achieved after reconditioning at a pH below 4.5.

    At present, traditional inhibitors applied for selective flotation of fluorapatite from dolomite generally own low selectivity, high toxicity, large dosages and high costs. Thus, this research offers a novel non-toxic and eco-friendly dolomite depressant, 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTCA), for selective flotation of fluorapatite with sodium oleate (NaOL) as a collector.
