  • PHOSPHORIC ACID PRODUCTION METHODS AND COMPOSITIONS
    Publication number: 20200109053
    Abstract: A wet process phosphoric acid production method comprises digesting phosphate-containing ore in a slurry comprising sulfuric acid, whereby phosphoric acid and calcium sulfate crystals are formed; and separating the phosphoric acid from the calcium sulfate crystals; wherein a defoamer and a poly(carboxylic acid), or salt thereof, having a weight-average molecular weight of less than 1,000,000 grams per mole (g/mol), are added to the slurry. The poly(carboxylic acid) can be a poly(acrylic acid), or salt thereof, and the defoamer can be a dialkyl sulfosuccinate salt and an aliphatic alcohol or a fatty acid ester. The method enhances separation of phosphoric acid from calcium sulfate crystals in wet process phosphoric acid production by any one of increasing the volume average particle size of the calcium sulfate crystals, increasing filtration rate, and reducing foam formation.
