2016-5-6  The Phosphate Beneficiation Flowsheet Phosphate Ore Mining. Electrically operated drag lines strip off the overburden from the mining area and deposit the phosphate matrix around a pump pit. Here it is sluiced with streams of high pressure water to the suction of a large centrifugal pump which transports the matrix slurry to the washing plant which may be a mile or two away. Washing and Screening Phosphate Rock
