Phosphate Flotation 1983

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.

Phosphate Beneficiation Process

Large scale mining and processing of phosphate is essential for operating at a profit. In the Florida area, Phosphate Beneficiation by flotation unlocked the door to vast tonnages of ore which in the past could not be recovered by conventional washing methods which saved only the coarser pebble phosphate. Many of the areas now being mined contain very little or no pebble phosphate, so the main ...

Phosphate flotation - W. R. Grace & Co.

Mar 22, 1983 · The amine used was commercially available from Westvaco Corporation as Amine 9AG, and was used as a 5% solution with kerosene. This is a well-known amine collector used in many phosphate flotation operations in the United States. The use of a kerosene extender is conventional in commercial phosphate flotation.
