Journal ArticleDOI
Adsorption mechanism of new mixed anionic/cationic collectors in a spodumene-feldspar flotation system
TL;DR: In this article, a mixed anionic collector sodium oleate (NaOL) and cationic collector dodecyl ammonium chloride (DTAC) demonstrate high selectivity for the flotation of spodumene from feldspar, and the optimal molar ratio of NaOL and DTAC is 9:1.
Journal ArticleDOI
Adsorption mechanism of mixed anionic/cationic collectors in Muscovite – Quartz flotation system
TL;DR: In this article, the flotation separation of muscovite from quartz was investigated using mixed sodium oleate/dodecylamine acetate (NaOL/DDA) collectors.
Journal ArticleDOI
Flotation and adsorption of mixed cationic/anionic collectors on muscovite mica
TL;DR: In this paper, the adsorption of dodecylamine acetate (DAA), sodium oleate (NaOL) and DAA-NaOL mixtures on muscovite mica were investigated through flotation tests, zeta potential measurements, and pyrene fluorescence tests.
Journal ArticleDOI
Effect of Pb 2+ ions on ilmenite flotation and adsorption of benzohydroxamic acid as a collector
TL;DR: In this article, the effects of Pb2+ ions on ilmenite flotation and adsorption of benzohydroxamic acid (BHA) as a collector were investigated using microflotation tests, zeta potential measurements, adsorization analysis, Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopic (XPS).
Journal ArticleDOI
Synergistic effect of mixed cationic/anionic collectors on flotation and adsorption of muscovite
TL;DR: In this paper, the synergistic effect of mixed cationic dodecyl amine-hydrochloride (DDA) and anionic collector sodium oleate (NaOL) at the air/water interface was investigated by the surface tension measurements.
