Apatite is acidulated with HCl to the stoichiometric stage required for making dicalcium phosphate. The reaction product when mixed with ammonium sulphate adequate to doubledecompose calcium chloride and dicalcium phosphate yields a nonhygroscopic product made up of Virtually all phosphorus during the drinking water-soluble form.

Apatite in Sri Lanka is mined from Eppawala (Eppawala Rock Phosphate or ERP). The finely ground product is utilised to be a direct application fertilizer for tea, rubber and coconut. ERP can be an indiscriminate mixture of a lot more soluble Principal crystals in addition to a less soluble secondary phosphate matrix full of ferruginous and aluminous compounds with a mean P2O5 content of thirty%. The first crystals can certainly be separated from your groundmass by mechanical separation to create selectively mined Principal crystals (SERP) which has greater P2O5 (35 to 42%) copyright application form ireland and lower R2O3 contents (around 1%) compared to matrix.
