Apr 30, 2020· Next, the phosphate is extracted and purified. Few phosphate deposits are pure enough for the separation process to be eliminated. The specific process used to separate phosphate from other minerals varies based on the exact composition of the ore. In most cases, however, water is used to turn the rock into mineral slurry, from which a combination of screening and filtering processes can
