Chemical Processing of Phosphate - Florida Industrial and ,
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 ac It is that acid that is used to make fertilizer
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 ac The sulfuric acid is then mixed with the phosphate to make phosphoric ac The phosphoric acid is the main ingredient in fertilizer, but can also be .
