  • Recovering molybdenite from ultrafine waste tailings

    2012-12-1 · The oil amount plays a significant role in the recovery of ultrafine molybdenite. As shown in Fig. 2, during conventional flotation, though the oil amount was increased to 1.0 kg/t, it forms loose and friable froth or just a little flocs in the flotation cell, because oil cannot act as bridging reagent but just as collector. Such friable mineral-bearing bubbles are very weak, and cannot be recovered completely.
