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 acidgypsum slurry in a digestion tank (Figs. and ).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 ...
World Phosphate Rock Reserves and Resources Executive Summary The amount of remaining phosphate rock reserves and resources worldwide has become an issue of speculation. It has been hypothesized that phosphorus (phosphate rock) production will "peak" in and then production will unavoidably decrease as the reserves are depleted.
