“…Line 4 is the FT-IR spectra of dolomite treated with NaOL with the pre-adsorption of SSZS. Line 4 shows that the characteristic adsorption peaks of NaOL did not exist and those peaks near 1201.49 cm −1 , 1022.13 cm −1 , and 960 cm −1 are considered to be the characteristic adsorption peaks of SSZS [40]. These results indicate SSZS can adsorb onto dolomite's surface; so, it can hinder the adsorption of NaOL onto dolomite's surface.…”

Flotation separation of magnesite from dolomite in the presence of SSZS (sodium silicate modified with zinc sulfate) as an inhibitor and NaOL (sodium oleate) as a collector has been studied via flotation tests, zeta potential measurements, contact angle measurements, and Fourier transformation infrared spectroscopy analysis (FT-IR). The flotation tests show that NaOL has strong collecting capacity in magnesite and dolomite flotation, so it is difficult to separate two minerals via flotation without inhibitors. SSZS is used as the depressant, which can selectively inhibit dolomite flotation and has little depression effect on magnesite. Zeta potential measurements, contact angle measurements, and FT-IR analysis indicate that SSZS can adsorb strongly onto dolomite’s surface and has a weak adsorption effect on magnesite. The adsorption of SSZS prevents NaOL from acting on the surface of dolomite. On the contrary, because there is little adsorption of SSZS onto magnesite, NaOL can still adsorb onto magnesite’s surface.
