The selective leaching method presents a new and innovative approach for the enrichment of low-grade phosphate raw materials. The use of acetic acid as a reagent in the leaching process allows for the selective dissolution of carbonates, potassium-, and aluminum-containing compounds, offering a promising solution for the improvement of the recovery rates of valuable phosphorus compounds. This study presents the results of research on the selective leaching of carbonates from low-grade phosphate raw materials and evaluation of its efficiency using a combination of SEM, energy-dispersion and chemical analysis, X-ray diffraction, differential thermal, IR-Fourier spectroscopic, and mineralogical analysis techniques. The results showed an increase in the content of phosphorus(v) oxide from 14% to 22% through the selective leaching process. The enriched phosphate raw materials were also found to be suitable for the production of phosphorus-containing products. This research highlights the potential of the selective leaching method to overcome the challenges faced in the enrichment of low-grade phosphorites and provide a more efficient and sustainable solution for the industry. |
