Mineral Processing. Swapan Kumar Haldar, in Mineral Exploration (Second Edition), 2018. 13.5.7.5 Flotation of Rock Phosphate Ore. Rock phosphate, the primary raw material for fertilizer and phosphoric acid, occurs as high-grade ore (+30% P 2 O 5), medium-grade ore (20%–30% P 2 O 5), and low-grade ore (15%–20% P 2 O 5).The very high-grade ore blends with medium …
