Abstract
A process for the improved beneficiation of phosphate ore in which the double float cationic (i.e., amine) floatation step is performed in two stages instead of the standard single stage, and which permits recovery of approximately two-thirds of the phosphate values that were previously lost in the amine tailings of the standard single stage process.
