| Abstract: | Specific to a micro-fine particle low grade Tantalum Niobium tailing which the distribution of Ta2O5 is more than 80% below 0.038mm, a gravity-flotation complex process using the method of pre-enrichment of centrifuge- flotation of rough concentrate is adopted, which bring good indexes with concentrate Ta2O5 Nb2O5 grade as 18.2547% 9.0838% respectively, Ta2O5 Nb2O5 recovery as 35.52%. 35.22%. This study has provided technical support for commercial utilization of such kind of micro-fine particle low grade Tantalum Niobium mine. |
