Chemical Processing of Phosphate - Florida Poly

Chemical Processing of Phosphate. The phosphate mineral as it exists in the ground is not soluble and is hard for the plant to access. To provide the plant with the phosphate it needs, in a form it can take up through its roots, the phosphate rock is converted to phosphoric acid.How phosphate is mined and processed,Processing The phosphate is sent to a chemical processing plant, or fertilizer manufacturing plant. Here, molten sulfur, shipped to Florida ports and trucked to the plant, is used to create sulfuric acid. The sulfuric acid is then mixed with the phosphate to make phosphoric acid.11.21 Phosphate Rock Processing,11.21 Phosphate Rock Processing 11.21.1 Process Description1-5 The separation of phosphate rock from impurities and nonphosphate materials for use in fertilizer manufacture consists of beneficiation, drying or calcining at some operations, and grinding.
