| Abstract: |
| Being as a new effective gravity equipment for the concentration of micro-sized tantalum-niobium materials,paving-carpet-centrifugal concentrator has the advantages of high concentration ratio over paving-carpet-Chute and the advantages of high recovery over centrifugal concentrator.In this paper,the employment of paving-carpet-centrifugal concentrator in treating the secondary fine ores from Yichun Tantalum-Niobium Mine was discussed.The tantalum-niobium concentrate, assayed 0.1515%(Ta,Nb)_2O_5, with 48.83% (Ta,Nb)_2O_5 being recovered was obtained when treating the ore at grade of 0.0113%(Ta,Nb)_2O_5,leaving the tailings containing only 0.0060%(Ta,Nb)_2O_5. |
