| Abstract: | The ore,dealt with in this paper,is a certain tungsten ore in Fujian province,China.The deposit, containing scheelite,wolframite and molybdenite,is granitic and joint vein type.The content of WO_3 in the run-of-mine ore is 0.25%,in which scheelite have the percentage of 41.35%,and wolframite have the percentage of 55.88%.The flowsheet used in the test is molybdenite flotation,sulfide flotation,tungsten ore flotation,and gravity separation for concentrate in tungsten ore flotation.The experiment result showed that the grade of first tungsten concentrate is 66.66% WO_3,and the recovery is 74.57%,and the grade of second tungsten concentrate is 39.24% WO_3,and the recovery is 16.58%,in addition,the grade of molybdenite concentrate is 12.21% Mo,and the recovery is 77.63% |
