Advanced Foreign Technologies for the Complex Processing of Low-grade Carbonate Phosphorites and Possibilities of Their Application to Local Raw Materials

Year: 2026

Type: article

Abstract: This study evaluates advanced global methodologies for processing low-grade Central Kyzylkum carbonate phosphorites (CaO/P2O5 > 1.6). Integrating two-step acid leaching (H3PO4 + H2SO4) and cascade "water-dilute acid" extraction bypasses mineral passivation, reduces overall acid consumption, and prevents rare earth element losses to phosphogypsum, achieving over 91% P2O5 and 93% REE extraction yields for sustainable fertilizer production.
