摘　　要：通过对毒砂与多金属硫化矿浮选分离因素的研究，提出用ＣａＣｌ２作为毒砂的抑制剂，使各浮选精矿产品的含砷量均达到０５％以下，有效地实现了浮选降砷，该工艺成功地用于工业生产，取得了很好的经济效益。On the basis of the study on flotation separation of arsenopyrite from polymetallic sulfide ore,CaCl_2 as a depressant which can be used in depressing arsenopyrite,has been developed The As contents of concentrates can be reduced to below 0 5% The new technology has been successfully used in industry,and high economic profit has been obtained
