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.

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).

Apparent Dip: Mineral Separations Part 2
2007-11-13 Two of the primary minerals geochronologists are interested in are non-magnetic (apatite and zircon). Minerals have slightly different magnetic properties, so the next step in separations is to take your cleaned heavy fraction from the gemeni table and run it through a Franz magnetic separator.

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.

2021-1-13 The objective of this research was to demonstrate the feasibility of selectively grinding dolomite from phosphate pellets by using a high-pressure roll mill (HPRM). Successful application will improve the separation efficiency of dolomite from apatite in subsequent downstream operations. High-dolomitic pebbles from four phosphate mines were tested.
