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 3032% P2O5 content. The growing fertilizer industry has increased the demand for phosphate rock from which superphosphates are produced. The fertilizer market is very competitive.
