Phosphate Flotation - Mineral Processing & Metallurgy
For Phosphate, flotation is, in general, very important to upgrading the phosphate rock and is employed in this study to beneficiate a 20% P2O5 feed content to a 30-32% P2O5 content. The growing fertilizer industry has increased the demand for phosphate rock from which super-phosphates are produced. The fertilizer market is very competitive.

Phosphorite - Wikipedia
The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5). Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5. This occurs through washing, screening, de-liming, magnetic separation or flotation.
