concentrator was converted from mechanical flotation cells to column flotation cells over a period of 2 years as part of a program to reduce plant operating costs. The ore is a volcanic phosphate ore containing approximately 20 %P 2 O 5 (27% to 28% CaO) primarily as apatite. Principal impurities are barite (9% to 15% BaSO 4), hematite (19% to ...

Based on the flotation test on raw rare earth ores in Bayan Obo Ore for mineral processing, it was found that the activation of apatite by polyacrylamide (PAM) flocculant, used in beneficiation backwater in the flotation of rare earth ores mainly contributes to the high phosphorus content in 58% rare earth concentrate. The mechanism of the ...

The effects of Ca2+, Mg2+, Al3+, and Fe3+ on the flotation behaviors of apatite, dolomite and quartz were investigated through a micro-flotation test, and the influence of calcium ions on the flotation of these minerals was further elucidated by solution chemistry study, zeta potential measurement, and X-ray photoelectron spectroscopy (XPS) analyses.

Most apatite concentrates, essential for the fertilizer industry, are produced using froth flotation, where collectors play a pivotal role. Although vegetable oil-derived surfactants have been used for decades in flotation processes, raw materials which do not compete with human or animal nutrition deserve special attention.

The application of nanobubbles through flotation of coarse apatite tailings evidently improved the process' metallurgical responses compared to flotation by conventional bubbles only. 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 ...
