针对西藏甲玛铜钼矿石进行选矿工艺试验研究。该矿石中主要目的矿物为黄铜矿、铜的次生矿物及辉钼矿。通过铜钼混合浮选-铜钼混合精矿再磨后铜钼分离的选别工艺流程及适宜的药剂制度,取得了较好的选矿指标。小型闭路试验获得的指标为:钼精矿品位47.71%,钼回收率73.20%;铜精矿品位32.11%,铜回收率94.22%;铜精矿含金16.65 g/t,含银351.7 g/t,金回收率47.88%,银回收率67.30%。
Experimental Study on Beneficiation Process of Cujia Molybdenum Ore in Tibet. The main minerals in this ore are chalcopyrite, copper secondary minerals and molybdenite. Through copper and molybdenum mixed flotation - copper and molybdenum mixed ore after grinding separation of copper and molybdenum separation process and the appropriate pharmaceutical system, and achieved good dressing indicators. The indexes obtained by the small-scale closed-circuit test are as follows: molybdenum concentrate grade 47.71%, molybdenum recovery 73.20%, copper concentrate grade 32.11%, copper recovery 94.22%, copper concentrate 16.65 g / t, silver 351.7 g / t , Gold recovery rate of 47.88%, silver recovery rate of 67.30%.
