Apatite Flotation Tailing

Froth flotation is the most important concentration method for beneficiating phosphate ores [2], [3].In this process, most collectors used worldwide are fatty acids obtained from vegetable species as byproduct of different industries, e.g., tall oil, a byproduct of the paper industry [4], [6].However, the investigations on alternative sources are being encouraged as …

The results of the confirmatory experiments of apatite flotation, which were performed using different types of water (freshwater, tailing dam water (without treatment) and water treated with DAF in different conditions) showed that the highest values of P 2 O 5 recovery and grade were obtained when the DAF process was performed with a pre ...

The recovery and grade of apatite in a flotation tailing portray gradual descent followed by subsequent ascent. Likewise, the DDALA dosage of 1.5 × 10 −4 mol/L marks a turning point in the trends of apatite recovery and grade in a flotation tailing. These results from the mixed mineral flotation experiments affirm the conclusions drawn from ...

This work presents the results obtained during flotation of fine-grained apatite-bearing tailings provided from the Kovdor concentration plant in a laboratory cell and a pilot-scale column.

The amphiphilic collectors investigated for apatite flotation include α-benzol amino benzyl phosphate acid, dodecylaminomalonic acid, dodecylglutamic acid, and sodium N-dodecyl-β-amino propionate ... with residual mineral particles being accumulated as a flotation tailing. Separate measurements were taken for the weights of the floated and ...

The application of nanobubbles through flotation of coarse apatite tailings evidently improved the process' metallurgical responses compared to flotation by conventional bubbles only. ... Finally, it is proved that the …

Conventionally, froth flotation has been used to separate phosphate minerals from interfering gangue via their distinct properties [7], [8].Significant research on the flotation of apatite has been conducted, but most previous studies focused on the flotation of single gangue minerals, and rarely considered the flotation of apatite containing silicon and calcium impurities …

Water from a tailing dam of an apatite processing industry has been treated by this technique and the produced water used in the flotation of apatite in column. Results have shown that the use of recycling water after the wastewater treatment proposed in this work led to a good performance of apatite flotation, leading to recovery (80.5%) and ...

The flotation procedure was as follows (1) 2.0 g of the single mineral or mixed minerals (i.e., apatite and dolomite, a mass ratio of 3:2): were placed into a plexiglass cell filled with deionized water (25 mL) and agitated for 1 min to obtain a uniform pulp; (2) P (AA-AMPS) (if necessary), pH regulators, and NaOl were added successively at 2 ...

The results indicated that nanobubble flotation of the as-received apatite tailings (−850 μm) was an attractive option that can minimize the CO 2 footprint of mineral processing by eliminating regrinding. The nanobubbles generated with surfactants (collectors and frothers) could cause a decrease in grade, mainly because of the increased ...

Commonly, reverse flotation flow is employed to separate apatite from dolomite, in which the apatite is depressed by sulfuric acid (H 2 SO 4) and the dolomite is floated by fatty acids. The major drawback of this flotation strategy is the inefficiency of the collector, since fatty acids cannot float dolomite well in weakly acidic slurries (pH 4 ...
