  • Selective flotation of scheelite from calcite A novel

    Sodium oleate (NaOl) has been widely used as a collector for the scheelite flotation. However, low selectivity of NaOl and large amount of sodium silicate (SS) needed remain tough problems. In this study, octyl hydroxamic acid (HXMA 8) was used as an associate collector with NaOl in scheelite flotation.
