TL;DR: In this paper, the effect of sodium alginate on the flotation separation of scheelite from calcite and fluorite using sodium oleate as collector was investigated using zeta potential measurements, contact angle measurements and FTIR.

TL;DR: In this article, the results of zeta potential measurements and FTIR spectra analysis demonstrated that sodium phytate adsorbed on the calcite surface and hindered the subsequent chemisorption of sodium oleate.

TL;DR: In this paper, a dextran sulfate sodium, a medical intermediate rich in sulfate group, was introduced as a potential depressant for calcite and fluorite in scheelite flotation.

TL;DR: In this article, the results of zeta potential measurements and FTIR spectra analysis demonstrated that sodium phytate adsorbed on the calcite surface and hindered the subsequent chemisorption of sodium oleate.

TL;DR: In this paper, the depression performance of poly (acrylic acid-co-maleic acid) sodium salt (PAMS) acting as a new depressant was evaluated via the flotation experiments, when sodium oleate (NaOl) was employed as the collector.

TL;DR: In this article, a promising method of improving the sulfidization flotation of smithsonite through surface modification with ammonia was proposed, which increased the amount of sulfide ion species adsorbed onto the mineral surface, thereby facilitating the attachment of xanthate species onto the sulfified mineral surface and promoting its hydrophobicity.

TL;DR: Xanthan gum (XG), a clean, non-toxic macromolecular polysaccharide, was studied as a depressant in the flotation separation of scheelite from calcite as mentioned in this paper.

TL;DR: In this article, the depressed performance and adsorption mechanism of HPMA on the dolomite and apatite surfaces were studied through flotation tests and surface analyses.
