20 mesh is treated by two-stage flotation. The flotation process uses hydrophilic or hydrophobic chemical reagents with aeration to separate suspended particles. Phosphate rock mined in North Carolina does not contain pebble rock. In processing this type of phosphate, 2-mm (0.078 in.) or 10-mesh screens are used.

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.

The level of beneficiation of any phosphate be it simply washing, flotation or thermal treatment has a considerable effect on the overall economics. Once again I must repeat that it is not the BPL or P 2O 5 content of a phosphate that has the main effect on the production cost but it is the CaO/P 2O 5 ratio. However the effect of the impurities ...
