【Abstract】 The test of comprehensive recovery of valuable elements in polymetallic antimony sulfide was carried out according to the properties of the ore. The results show that the antimony concentrate,silver-lead bulk concentrate and arsenic concentrate can be obtained by using part bulk-separation flotation flowsheet.The grade and the recovery of Sb is 56.27%and 77.92%in the antimony concentrate.The grade and the recovery of Pb is 26.63% and 61.34%,the grade and the recovery of Ag is 2500g/t and 68.84% in the silver-lead bulk concentrate.The grade and the recovery of As is 10.31% and 83.09% in the arsenic concentrate.The wolfram in the tailings of sulfide flotation was concentrated by gravity-magnetic concentration,with the grade of WO 3 raising from 0.24% to 9.28%,the recovery of WO 3 reaching 74.77%.更多还原
