The accumulation of phosphogypsum (PG) in the phosphorus chemical industry poses significant environmental challenges. Therefore, developing a harmless utilization method is crucial for alleviating these burdens and promoting sustainable practices. In this study, PG was used as flotation inhibitor, enabling separation apatite dolomite based on main components dissolution behavior PG. A microflotation study revealed that 0.875 g/L selectively inhibited when sodium oleate (NaOL) concentration 1.5 × 10-4 mol/L, reducing recovery 76% to 10% at pH range 7-11. Conversely, remained above 90% 7-9 only slightly 9-11. When CaSO4·2H2O CaHPO4·2H2O were added inhibitors, they also dolomite, though their effects weaker than Measurements contact angles, zeta potentials, adsorption capacities indicated enhanced hydrophilicity hindering NaOL thereon, while it had little effect floatability apatite. Atomic force scanning electron microscopy selective adsorbed surface, altering its properties, weakly surface minimal impact properties. solution composition microthermal results showed CaSO4 CaHPO4 are effective inhibition. X-ray photoelectron spectroscopy time-of-flight secondary ion mass spectrometry confirmed Ca Mg sites surface. Molecular dynamics simulations interacts with can promote dolomite. Utilizing inhibitor provides novel approach environmentally safe use resources.

Towards a European sustainable beneficiation of rare earth elements bearing minerals: a review

The Science of The Total Environment, Год журнала: 2025, Номер 980, С. 179386 - 179386

Опубликована: Май 3, 2025

This review explores the multifaceted aspects of sustainable extraction rare earth elements (REEs) bearing minerals within Europe, stressing exploitation local deposits, that together with integration cleaner and greener approaches (including circular economy approaches) might help to reduce dependency on imports contribute a economy. The mineralogical characteristics distribution REEs in European deposits are examined, alongside current emerging beneficiation techniques aimed at enhancing efficiency sustainability. Key challenges, such as mineral complexities (technological economic limitations), radiochemical environmental impacts, well social acceptance, critically assessed. Innovative new aim be applied mainly primary sources (mineral deposits) but also secondary (secondary raw materials) presented suggested for extraction. Finally, Europe's over-dependence foreign countries prospects discussed, outlining strategic roadmap achieving economically viable practices Europe. comprehensive holistic analysis stresses importance an integrated approach combines developing unexploited resources boosting recycling initiatives, technological innovation, implementing standards community engagement foster REE supply chain
