• Nuinsco reported metallurgical tests at its Prairie Lake critical minerals and phosphate project in Ontario produced marketable phosphate, REE concentrates.
• Carbonatite and ijolite composites consistently exceeded 30% P2O5 concentrate grade from feed grades up to 3.73% and 3.0%.
• Best carbonatite test delivered 77.5% P2O5 recovery with 32.8% P2O5 concentrate; ijolite runs produced about 70% stage recoveries.
• Tests showed low thorium, uranium, cadmium, chloride in concentrates; REE grades rose broadly in line with P2O5 upgrading.
• Next work targets dense media separation, reagent tuning; aims for higher-grade phosphate, over 80% recovery, REE co-concentrate.
