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.
