10%Repeated cleaning and beneficiation of the upper-zone ore resulted in concentrate compositions of 57.34wt% of Ta 2 O 5 and 5.41wt% of Nb 2 O 5. Washing the tantalite concentrates using 1vol% KOH and 1 M H 2 SO 4 led to the removal of thorium and uranium radioactive oxides from the concentrate.
Niobium minerals, especially columbite, are also associated with other valuable minerals, such as tantalum, zircon and rare earth minerals. Pyrochlore and a mixture of pyrochlore and columbite have different origins, and therefore, beneficiation of pyrochlore and columbite are different from that of the mixed tantalum niobium ores.
