Fig. 2 demonstrates the relationship between flotation recovery of columbite-tantalite and pulp pH under different reagent schemes. The results show that when columbite-tantalite was conditioned with 1.2 × 10 −3 mol/L BHA, its maximum recovery only reached approximately 17.0 % at pH 8.0. Although the concentration of BHA increased to 2.4 × 10 −3 mol/L, only 28.4 % of minerals were …
