In the flotation of sphalerite, the concomitant flotation of sulfidic (pyrite) and nonsulfidic gangue (silica) minerals significantly reduces the grade of the float concentrate. Laboratory scale experiments have been conducted to investigate the effect of tert dodecyl mercaptan (TDM) as a collector on the flotation of sphalerite. The addition of only 160g/t copper sulfate, which is 30% of that which...
Solution chemical calculation, zeta potential measurement and flotation test were introduced to verify the effective inhibiting component and illustrate the inhibition mechanism of ZnSO4 and Na2CO3 as a combined inhibitor for talc. Solution chemical speciation calculations indicated that the formation of solid state Zn(OH)2 occurred in all initial concentration ranges of ZnSO4. The higher the initial...
Effects of the sodium salt of N,N-dimethyldi-thiocarbamate (DMDC) in the absence and presence of butyl xanthate (BX) on the flotation of chalcopyrite, sphalerite, and marmatite have been investigated. Probable metal complexes and adsorption modes are inferred from UV–vis spectra, Fourier transform infrared (FTIR) and first-principles study. The results show that the presence of iron can reduce the...
