Improving flotation separation of apatite from dolomite

01/09/2020· In the apatite flotation process, carbonate minerals especially magnesium-bearing dolomite are easy to enter into apatite concentrates, reducing the quality of concentrate products and causing excessive acid consumption in downstream processing.

MgO Dolomite Flotation

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

Flotation of Dolomite from Apatite MDPI

Abstract:In this study, the effect of sodium pyrophosphate (NaPP) on the separation of apatite from dolomite by flotation was systematically investigated. Flotation results revealed that NaPP could selectively depress the flotation of apatite, thus realizing the separation of apatite from dolomite.

Effect of Sodium Chloride on Dolomite Flotation

In this process, the feed is conditioned at pH 10, followed by reconditioning at a pH lower than 4.5, before flotation. Dolomite is selectively floated out following the two-stage conditioning step. The addition of sodium chloride to manipulate electric double layer charges can selectively depress apatite, leaving dolomite flotation unaffected.

Minerals Free Full-Text A Review of Flotation

The flotation separation is effective at both acidic and alkaline pH; however, flotation is not recommended at acidic pH due to the high consumption of collectors used by the lattice dissolution of dolomite. The isoelectric point of pure magnesite and dolomite were reported in the pH ranges of 6.5–6.8 and 5.5–7.6, respectively. Several reagents are capable of changing the hydrophobicity of
