In this study, conducted in a laboratory scale, eight different depressants, organic and inorganic, were tested in the direct flotation of a Brazilian silicate-carbonate phosphate ore. The best performance in the depression of calcite and silicates was achieved with cassava starch.

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.

sant on selective flotation of scheelite and calcite when sodium oleate was used as a collector. The single mineral micro-flotation results indicate that that the SH offers excellent selective depression of calcite from scheelite. Hence mixed scheelite and calcite (the WO 3 grade in original mixture is about

Froth flotation is one of the promising techniques acquiring large potential in the separation of calcite from such phosphate ores. In our previous work "Part I" of this project, an extensive experimental study using a conventional flotation cell for phosphate beneficiation was carried out and the optimum flotation parameters were achieved.

This laboratory scale investigation addressed two different process routes for the concentration of a phosphate ore bearing a silicate-carbonate gangue: (i) bulk apatite and calcite flotation followed by calcite flotation in the presence of phosphoric and citric acids; ... mechanism of apatite depression and carbonates flotation in slightly ...

Calcite samples from different origins and genesis (Table 1) were first purified and characterized, and then submitted to dissolution and flotation experiments. Most of the calcite samples (CAM, CCI, CCJ and CSQ) were purified from phosphate ores that are exploited by different mining groups. The exceptions are the opaque

The observed optimum flotation of calcite and dolomite by carboxylic acids as a function of the starch consumption, and the subsequent depression of flotation, may be chiefly due to the adsorbed conformation structures of the starch molecules to the strength of the hydrogen bonds with the surfaces of hydrated minerals.

Abstract: In the flotation of scheelite ore containing fluorite and calcite, the treatment of calcite is important to obtain satisfactory scheelite and fluorite concentrate. It is better in scheelite rougher flotation to activate calcite with Na 2 CO 3 and to float it into scheelite rough concentrate,than to depress calcite into fluorite flotation operation like the conventional process.

Calcite-Apatite Flotation - Columbia University. carbonate and phosphate can be somewhat altered.. in the presence of one another. Carbonate and phosphate species can be expected to chemisorb - --on the calcite surface and thus can compete with oleate for the surface Casites resulting in flotation depression.

The effects of sodium silicate, gum arabic and sodium tripolyphosphate on the zeta-potentials and Hallimond tube flotation of calcite, apatite and dolomite by sodium oleate were studied.

measurements to find out the mechanism of cellulase depression of phosphate. The findings from the single minerals tests were used to develop a selective flotation process for recovery of phosphate minerals from the natural phosphate ore. The flotation experiments were carried out to apply this new process using the calcareous phosphate ore.
