Igneous ores are generally associated with Phanerozoic carbonatites and silica-deficient alkalic intrusions that typically average 5 to 15 wt % P 2 O 5, which can be beneficiated to high-grade concentrates of at least 30 wt % P 2 O 5 with few contaminants. Carbonatites are typically the smallest and youngest parts of a carbonatite-alkaline rock
