俄罗斯某富砷锑矿锑品位为8. 78%、砷含量为1. 40%. 锑主要以辉锑矿的形式存在,砷主要以毒砂的形式存在,毒砂嵌布粒度微细,少量辉锑矿存在于毒砂裂缝中,增加了辉锑矿分选的难度. 为给该矿石选矿工艺提供依据,对其进行了浮选流程试验. 结果表明:在磨矿细度为-0. 074 mm占75%条件下,以硝酸铅为锑活化剂、腐植酸钠为砷抑制剂、丁黄药为捕收剂,经1粗3精1扫闭路流程浮选,得到的锑精矿锑品位为59. 22%、回收率为84. 58%、砷含量为0. 73%. 试验结果可以为该矿石选矿工艺流程的确定提供依据.

There is 8. 78% antimony and 1. 40% arsenic in a arsenic-bearing antimony ore from Russian. Antimony mainly exists in form of the stibnite,and arsenic mainly in form of arsenopyrite. Arsenopyrite are fine disseminated,a small a-mount of stibnite exists in arsenopyrite cracks,making it difficult to have stibnite efficient separation. In order to provide techni-cal basis for beneficiation of the ore,flotation experiments was conducted on the ore. Results indicated that:with the grinding fineness of 75% -0. 074 mm,using lead nitrate as antimony activator,humic sodium as arsenic inhibitor,butyl xanthate as col-lector,via one roughing-three cleaning-one scavenging closed circuit process,antimony concentrate with 59. 22% antimony,0. 73% arsenic,and antimony recovery of 84. 58% is obtained. The test results provide technique basis for the concentration process determination of the ore.
