Procedure

The sulfuric acid fed into the extraction battery reacts with the phosphate in the wet process phosphoric acid to form sulfate and phosphoric acid. The sulfuric acid is converted into sulfate which is easily extracted into the aqueous phase. On the other hand, the phosphate is converted into phosphoric acid which is easily extracted into the solvent phase. The fact for increasing the yield of phosphoric acid by the addition of sulfuric acid is given by such effect of sulfuric acid.
