Improving Flotation Separation Of Apatite From Dolomite

Sep 01, 2020 Flotation separation of apatite and dolomite is very difficult using NaOl alone. PAMS is selectively adsorbed onto dolomite due to its strong bonding to Mg sites. The adsorption of NaOl onto dolomite is hindered strongly by the addition of PAMS. Greater amounts of NaOl is adsorbed on apatite than dolomite in the presence of PAMS.

Selective Flotation Separation Of Apatite From Dolomite

Mar 01, 2021 Efficient flotation separation of apatite from dolomite can be realized by P AA-AMPS. P AA-AMPS is an eco-friendly and efficient depressant of the dolomite flotation. Much more adsorption of P AA-AMPS occurs onto dolomite than apatite. The pre-adsorption of P AA-AMPS prevents strongly NaOl adsorption onto dolomite.

Flotation Separation Of Quartz From Apatite And Surface

Feb 25, 2019 However, the separation performance of the flotation was lower at pH 7 regardless of the collector concentration. Thus, more collector molecules are adsorbed on the quartz surface than the apatite surface at pH 3 and 5 10 5 M of collector, resulting in separation of quartz and apatite. The extended DerjaguinLandauVerweyOverbeek DLVO theory, which considers the hydrophobic interaction energy, revealed that the improved flotation
