Abstract

Mongolia possesses over 3.6 billion metric tons of phosphate resources, predominantly located in Khuvsgul and Zavkhan Provinces. Despite this abundance, the country lacks industrial-scale phosphate beneficiation and fertilizer production, resulting in over 90% import dependency. Current national fertilizer consumption is estimated at 60,000–70,000 metric tons annually, whereas agronomic assessments indicate a requirement of 250,000–300,000 tons annually to meet domestic food production targets.

This research examined the composition and processing potential of phosphate concentrate obtained by flotation from the Burenkhaan phosphorite deposit. The concentrate contained 35.91% P₂O₅, 50.53% CaO, and 78.47% BPL, primarily composed of fluorapatite (77.1%). Acid leaching with 40–60% phosphoric acid (H₃PO₄) at 80–100 ℃ for 5–20 min produced high-quality triple superphosphate (TSP) fertilizer, containing 42.85–55.28% total P₂O₅, with 100% plant-available phosphate and up to 100% water solubility. The chemical composition and physicochemical properties of the produced TSP fertilizer and phosphate concentrate were analyzed using XRD, XRF, ICP-OES, TGA/DTG, and FTIR spectroscopic techniques.

The results confirm the technical and economic feasibility of processing Burenkhaan phosphate to produce high-quality fertilizers, providing a pathway for import substitution and sustainable agricultural development while supporting Mongolia’s strategic goal of fertilizer self-sufficiency.
