Effects of Metal Ions on the Flotation of Apatite ...

The effects of Ca2+, Mg2+, Al3+, and Fe3+ on the flotation behaviors of apatite, dolomite and quartz were investigated through a micro-flotation test, and the influence of calcium ions on the flotation of these minerals was further elucidated by solution chemistry study, zeta potential measurement, and X-ray photoelectron spectroscopy (XPS) analyses. The results indicate that an appropriate ...

Flotation of Dolomite from Apatite - MDPI

The desliming operation to discharge ultrafine particles less than 20 µm prior to concentration by flotation is a common practice in phosphate ores beneficiation plants. The first industrial application for the beneficiation of the phosphate material with particle sizes <44 µm in Brazil was in the Araxá plant concentrator in the beginning of the 1980s.

The hydrodynamic conditions in the cell govern the formation of flocculated foams with highly dispersed air bubbles; increase of hydraulic resistance in the slurry leads to the formation of concentrates with large P 2 O 5 contents, but at lower velocity; as the solids content of the slurry increases, the relative flotation velocity at first increases, then, in dense slurries, decreases.

A selective dolomite flotation process has recently been developed at the University of Florida whereby a two stage conditioning technique is utilized to remove MgO impurities. Previous investigations have mainly involved studies on synthetic apatite/dolomite mixtures in a microflotation (Hallimond) cell. The collectors employed were of laboratory reagent grade and flotation was carried out in ...
