Chemical Processing of Phosphate
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.

Phosphate Rock
The use of phosphate rock requires the removal of impurities, a process specific to the grade of the deposit. Mined phosphate rock is washed, crushed, screened, and floated before chemical processing can take place. Beneficiation steps may include separation of particles, crushing, and grinding to separate the phosphate from other material.
