The Effects of Calcium Ions on the Flotation of

The effects of Ca2+ ions on the flotation of sillimanite using dodecylammonium chloride as a collector were investigated by microflotation tests, zeta potential measurements, solution chemistry analysis and molecular dynamics (MD) simulation. The microflotation results indied that Ca2+ ions remarkably inhibit the flotation of sillimanite in the pH range of 2.0–9.0. The point of zero

Cell and Column Flotation Studies of a Low Grade Siliceous

Aug 03, 2014 · The results of column flotation studies clearly suggest that a limestone concentrate assaying around 50 percent of CaO with less than 8.0 percent SiO 2 suitable for cement manufacture could be achieved. Proper utilization of the waste, solid as well as liquid, generated from the flotation proposes was also discussed.

The Improvement Effect of Dispersant in Fluorite Flotation

Abstract. Different dispersants were added in the dispersion process to improve the efficiency of fluorite flotation. The types and dosage of dispersant on the improvement of fluorite flotation were investigated when the sodium polyacrylate (SPA) was used as the dispersant and its addition is 0.5%, the concentrate grade of CaF 2 increased from 90% to 98% and the fluorite recovery increased

Flotation studies on low grade graphite ore from eastern India

A low grade graphite ore from eastern India was beneficiated by flotation to improve its quality. The ore was composed of 87.80% ash and 8.59% fixed carbon. Primary coarse wet grinding (d 80: 186 μm) followed by rougher flotation in Denver flotation cell using diesel as collector and pine oil as frother yielded a rougher concentrate.

Surface Energy and Induction Time of Fine Coals Treated

Subbituminous coal with low mineral inclusion was found to have a relatively low surface energy, and thus a high floatability, but very poor selectivity was observed, which was reflected in lengthened induction time. When dynamics of flotation behaviors are involved, flotation results can be better interpreted by induction time.
