apatite mineral separation

Improving flotation separation of apatite from

2020-9-1  However, due to the similar active sites (calcium or/and magnesium species) on the cleavage surfaces of apatite and associated carbonate minerals (Filippova et al., 2018, Hirva and Tikka, 2002), these minerals often exhibit similar reactivity to these fatty acids collectors, resulting in poor selectivity in flotation separation of apatite from carbonate minerals (Pugh and Stenius, 1985).

The flotation separation behavior of apatite from

2020-12-1  The separation of apatite from calcite has been recognized as one of the most difficult subjects in mineral processing owing to their similar surface properties, thus finding high-efficiency depressants become the key for the separation.

Improved Flotation Separation of Apatite from Calcite

2019-9-18  Apatite (Ca 10 (PO 4) 6 F 2) is the most important phosphate mineral, and flotation is the main beneficiation method to separate apatite from its major gangue mineral calcite (CaCO 3). Till date, fatty acids and their salts have been widely used as collectors in the apatite/calcite flotation separation due to their low cost and strong collecting ability, but their selectivity is limited.

2019-12-11  The floatability of apatite and calcite in the absence and presence of depressant PAAS using sodium oleate (NaOL) as collector was investigated by microflotation experiments. The selectively depression mechanism of PAAS was revealed by wettability analysis of the mineral surfaces and X-ray photoelectron spectroscopy (XPS) analysis.

Separating Dolomite Apatite by Flotation

2018-8-28  Since an optimum separation of the mineral mixture was achieved by reconditioning at pH below 4.5, further studies were conducted to understand the mechanisms of selective flotation under those conditions. Selective flotation of dolomite from apatite upon acid reconditioning can be due to: (a) Selective desorption of the collector from apatite
