This invention provides a process for the beneficiation of phosphate ores having a magnesia-rich carbonate-containing gangue and a silica-containing gangue, which process comprises subjecting the phosphate ore particles to controlled attrition to remove at least a portion of the magnesia-rich carbonate-containing gangue; and subjecting the phosphate ore resulting from attrition to a plurality of flotations to remove the remaining magnesia-rich carbonate-containing gangue and the silica-containing gangue and to recover a concentrated phosphate product, the flotations including sequentially a phosphate flotation, a silica flotation and a carbonate flotation. Alternatively, the controlled attrition can be employed after the silica flotation and prior to the carbonate flotation.
