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

how phosphate rock crushed

The phosphate rock is mined, dried, crushed until 60–70% of the rock is less than 150 μm in diameter, and then continuously fed into the reactor along with sulfuric acid. The reaction combines calcium from the phosphate rock with sulfate, forming calcium sulfate (CaSO 4 ), commonly referred to as gypsum.

Method for manufacture of phosphoric acid from

Crushed phosphate rock from line 26 is introduced to reactor 24 wherein it is mixed with dilute phosphoric acid which is recycled from the process through line 28. Reactor 24 is equipped with a stirrer and the slurry is mixed for a time period sufficient to convert the phosphorus values in the rock to mono calcium phosphate. Generally, the
