    THE PROCESS. The first module is Module 1A where the phosphate rock is selectively digested in diluted hydrochloric acid (HCl). This reaction produces a slurry of undigested phosphate rock as a solid with phosphate and calcium chloride (CaCl 2) in solution.In Module 1B, the phosphate solution is treated with CaCO 3 to obtain dicalcium phosphate dihydrate (CaHPO 4.2H 2 O, DCP) crystals and
