  • Phosphate Rock - an overview ScienceDirect Topics

    Phosphate rock of 70 to 75% BPL, or as high as is reasonably obtainable, is finely ground in a ball mill and then mixed with cooled recycled phosphoric acid-gypsum slurry in a digestion tank (Figs. 10.3 and 10.4).At this stage the only reaction which occurs is between acid and any carbonates present in the rock, and between phosphates and low concentrations of sulfuric acid which may be ...

  • Phosphate Rock - an overview ScienceDirect Topics

    Arthur L. Kohl, Richard B. Nielsen, in Gas Purification (Fifth Edition), 1997. Operating Data. In the production of superphosphate fertilizer from phosphate rock, the rock is normally pulverized, mixed with sulfuric acid, and discharged into a den where the reaction between rock and acid proceeds.The fresh superphosphate is then removed from the den by an elevator and conveyed to storage for ...
