摘　　要：通过对西藏某斑岩型铜钼矿混合浮选优化试验研究,确定最佳工艺流程和药剂制度,闭路试验可获得精矿产率1.76%,混合精矿Cu 28.65%、Mo 2.71%,Cu回收率88.45%,Mo回收率86.01%的选别指标,伴生银被富集到混合精矿中,银含量达到85 g/t,为矿山资源评价提供了依据。By the experimental research on bulk flotation of a porphyry type copper - molybdenum ore in Tibet, the optimum technological conditions and reagent system were determined. A bulk concentrate with 28.65% of copper and 2.71% of molybdenum was obtained with the yield of 1.76% and by a recovery of 88.45% copper and 86.01% molybdenum in closed circuit experiment. The silver was also enriched to the bulk concentrate and the grade of silver was 85 g/t. The research provided evidence for resource evaluation in the mine.
