Phosphate salts are inorganic compounds containing the phosphateion (PO43 -), the hydrogen phosphateion (HPO42 -), or the dihydrogen phosphateion (H2PO4 -), along with any cation.
Furthermore, as the ratio of phosphate to sulfate increases the product quality (grade and recovery) improves, which emphasizes the effect of the phosphateion as a depressant for phosphate minerals.
