After the gypsum precipitation stage, triple superphosphate is obtained by reacting the phosphoric acid with further phosphate rock. Otherwise, various ammonium phosphate fertilizers can be produced by reacting the phosphoric acid with ammonia. The uranium is normally recovered from the phosphoric acid (H 3 PO 4 – bearing about 28% P 2 O 5) by some form of solvent extraction (SX). Kamorphos is .
