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
