摘　　要：针对黑龙江某铜钼矿石品位低、嵌布粒度较细且不均匀的特点,试验研究采用铜钼混合浮选、粗精矿再磨再选的选矿工艺,当原矿铜品位0.61%、钼品位0.013%时,获得混合精矿含铜23.59%、钼0.31%,铜回收率90.02%,钼回收率70.27%的良好指标。According to the characteristics of low grade, fine and uneven dissemination size of the copper - molybdenum ore from a copper - molybdenum mine in Heilongjiang province, a Cu - Mo bulk concentrate of 23.59% Cu and 0.31% Mo was obtained from the feed ore containing 0.61% Cu and 0.013% Mo by the dressing process of Cu - Mo bulk flotation then rough concentrate regrinding and flotation with Cu recovery of 90.02% and Mo recovery of 70.27%. The processing indexes were good.
