Wet Grinding Phosphate Rock In An Acidic Slurry

The high acidity of the grinding slurry is neutralized to some extent by acid neutralizing impurities contained in the raw phosphate rock being ground in the ball mills and in the coarse fraction of ground phosphate rock which in most plants utilizing wet grinding is recycled from cyclone separators or other types of particle size separators.
