Very finely ground phosphate rock (95% to 98% < 100 mesh) is mixed with phosphoric acid. With rock of 34% P 2 O 5 content, about 2.6 kg of acid P 2 O 5 is required per 1 kg of rock P 2 O 5. The phosphoric acid used is merchant-grade acid at 52% P 2 O 5 concentration. This is diluted by scrubber liquid to about 48% P 2 O 5.

Regulating heavy metals through blending As stated in part 2 of this blog series, the typical target limit for cadmium in superphosphate fertilizers is <280 ppm. It might be concluded, therefore, that the answer is to simply source phosphate rock with cadmium levels (in fluorapatite) below this limit as a production feedstock.
