To modify surface roughness and improve flotation performance, hydrochloric acid etching pretreatment was performed on magnesite dolomite. Flotation tests disclosed that corrosion improved the kinetics recovery rates of Under pulp pH 10 sodium oleate (NaOl) concentration 20 mg·L−1, dolomite after increased by 31.05% 29.20%, respectively, compared with those before etching. Adsorption density proved adsorption NaOl higher than etching, implying drives adsorption. Zeta potential analysis revealed reduces point zero charge Atomic force microscopy X-ray photoelectron spectroscopy results demonstrated modified dolomite, increasing magnesium (Mg) content calcium Mg contents surface. Contact angle measurements indicated slightly reduced contact between With present surface, angles significantly Therefore, is effective in improving floatability

Research advancement of efficient flotation separation technologies for magnesium-containing minerals

Deleted Journal, Год журнала: 2024, Номер 1(2), С. 140 - 156

Опубликована: Июнь 1, 2024

As high-grade magnesite and brucite resources (hereinafter referred to as magnesium-containing minerals) are decreasing annually, developing flotation separation technologies capable of efficiently economically extracting magnesium from low-grade minerals is necessary. Although efficient for well researched, related concepts not yet clarified. Moreover, the industrial development mineral limited by their low efficiency environmental problems. This limitation has inhibited full utilization minerals. study comprehensively discusses research progress minerals, focusing on crystal chemical surface characteristics gangue effect inevitable ions behavior, interaction effects advancement reagents. The aims clarify future direction provide theoretical support technical references an separation.

Novel Collector of a Dodecylpyridinium Chloride Ionic Liquid in the Reverse Flotation Separation of Muscovite from Apatite

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Янв. 23, 2025

Reverse flotation separation of muscovite from apatite using a dodecylpyridinium chloride (DPDC) ionic liquid as the collector was studied in this work. The microflotation results depicted that DPDC had strong collecting for but slight when phosphoric acid depressant weakly acidic pH value pulp, artificial mixture mineral showed reverse can be effectively achieved reagent scheme acid/DPDC, and better performance muscovite/apatite system than DDA. adsorption measurements indicated amount on surface less surface, zeta potential confirmed interaction occurred between while an extremely weak presence at ∼ 5.5. XPS analysis hydrogen bond surface. Thus, it inferred could used appreciation apatite.
