Chemical Processing of Phosphate - Florida Polytechnic

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. It is that acid that is used to make fertilizer.
