Sulfuric Acid → Phosphoric Acid

Participants

Reaction Steps

adding sulfuric acid to the crystallization slurry to react with at least the monocalcium phosphate to form calcium sulfate dihydrate and phosphoric acid, while maintaining the crystallization slurry at a soluble sulfate concentration of from about +0.5% to about +3.0%, the soluble sulfate concentration of the crystallization slurry being greater than the soluble sulfate concentration of the dissolving slurry;
