Arsenic K-edge X-ray absorption near-edge-structure extended fine structure data show that dominant oxidation state +5 5+ occupies S site picromerite.

The synergistic effect of sodium dodecyl benzene sulfonate (SDBS) on the flotation separation magnesite and dolomite using oleate (NaOL) as a collector has been studied through experiments, zeta potential measurements, contact angle Fourier transformation infrared spectroscopy analysis (FT-IR), particle size measurements transmittance measurements. experiments show that when synergist, SDBS, is added to collector, NaOL, collecting ability ion resistance NaOL can be improved so realized. Zeta FT-IR indicate SDBS co-adsorb surface magnesite. Particle also improve dispersion solubility in an aqueous solution, achieve effect.
