  • Rock Phosphate Creative Generation

    The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P2O5). Marketed phosphate rock is enriched (“beneficiated”) to at least 28%, often more than 30% P2O5. This occurs through washing, screening, de-liming, magnetic separation or flotation.Calculate the flow rates, Low-grade phosphate rock ,Low-grade phosphate rock can be upgraded by flotation processing. In this process the low-grade rock is grounded into a powder and suspended as a water slurry. The addition of small amounts of oil and other surface active agents causes the phosphate to adhere to air bubbles. By frothing the slurry with air, a phosphate rich foam floats off the
