Ta-Nb ore Featured The coarse concentrate obtained by the rough selection process is generally a mixed coarse concentrate, which needs to be further selected to separate a variety of useful minerals. The selection of tantalum and niobium Nanping cleaning of mineral surface with 6% hydrochloric acid solution, and then removing the weak magnetic and ferromagnetic minerals iron scrap, dried and sieved to + 0.2, 0.1 + -0.1mm, and three levels, namely, The strontium concentrate was obtained by a rough magnetic separation machine through one rough selection and one sweep. The selected results: 钽铌 钽铌 concentrate yield 0.0764%, containing (TaNb) 2O5 45.64% (Ta2O5 32.57%), recovery rate of raw ore 69.92% (Ta2O5 recovery rate 69.071%), the recovery rate of selected operations was 94.11%; Our PVC Foam Board Used For Pop, Signage, And Non-load-bearing Wood Replacement For Interior And Exterior Applications.
