Abstract

The solubility of YF3, CeF3, PrF3, NdF3, and DyF3 in solutions containing 0–4.496% mol/L (0–35 wt %) of H2SO4 and 0–27.6 g/L of H3PO4 (0–20 g/L of P2O5) at 20 °C was determined. Higher solubility in sulfuric acid solutions compared to that in hydrochloric and phosphoric acid solutions was attributed to the formation of fluorosulfate complexes M2(SO4)F4(M = Y, Ce, Pr, Nd, Dy). The effect of minor concentrations of the phosphate ions on the solubility of YF3, CeF3, PrF3, NdF3, and DyF3 in sulfuric acid solutions and the effect of fluoride ions on the recovery of lanthanides during sulfuric acid leaching from the phosphohemihydrate were discussed.
