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.
