Froth flotation of scheelite has regained new focus since the 2010s and research regarding floatability and reagents has made great progress over the years. The main objective was and remains the selective flotation of scheelite from other calcium-bearing minerals, in particular calcite, fluorite and apatite.

The beneficiation of MgO component in dolomite ore by froth flotation was investigated in this research. Dolomite is an important mineral resource as an industrial material, however, it is not abundant in quantity of resources and the grade of MgO in dolomite ore available in Japan is lowering after consuming for a long time.

A reverse flotation process for removing alkaline earth metal carbonate impurities particularly dolomite and calcite as the cell overflow from a flotation feed reagentized with water, a carbonate collector, a phosphate depressant and a pH regulator to about 20-30% solids and a pH of about 5.5-6.0. The phosphate concentrate is collected as the cell underflow.

Flotation feed material was conditioned at pH 10.0 with fatty acid followed by flotation of apatite and dolomite at pH 8. The float fraction was then reconditioned at a pH less than 4.0 for a selected time interval. After the addition of make-up water, dolomite flotation was carried out at pH 4.0 or below.

In flotation concentration, the mineral is usually transferred to the froth, or float fraction, leaving the gangue in the pulp or . tailing. This is . direct flotation. as opposed to . reverse flotation, in which the gangue is separated into the float fraction. Flotation is the most important and versatile mineral processing technique used in ...

3/22/1988· A process for recovering phosphate values from a finely divided ore containing the phosphate values and gangue such as an ore containing apatite, calcite and dolomite, by froth flotation includes the steps of suspending the finely divided ore containing the phosphate values and the gangue in a liquid at a pH of greater than 7; adding to the suspension a froth flotation collector comprising a ...

It was reported earlier that francolite and dolomite from south Florida deposits cannot be selectively floated using conventional conditioning with sodium oleate as the collector. However, dolomite could be separated from francolite if the minerals were first conditioned at pH 10 followed by reconditioning at a lower pH. An optimum separation was achieved after reconditioning at a pH below 4.5.

It is well documented that flotation has high economic viability for the beneficiation of valuable minerals when their main ore bodies contain magnesium (Mg) carbonates such as dolomite and magnesite. Flotation separation of Mg carbonates from their associated valuable minerals (AVMs) presents several challenges, and Mg carbonates have high levels of adverse effects on separation efficiency.

Moreover, dolomite is a sparingly soluble mineral with a K sp of 1 × 10 −19.35 (Chen and Tao, 2004). There may be too few Ca 2+ ions available to react with benzohydroxamic acid and to provide a sufficient degree of hydrophobicity. For monazite flotation, the three collectors appear to have achieved a good floatability at a pH at ...
