P-recovery by secondary nucleation and growth of calcium phosphates on magnetite mineral

Precipitation of calcium phosphates from supersaturated solutions seeded with magnetite powder (magnetite mineral, Fe 3O 4) has been studied in lab scale in the pH range 6.9–7.7. While the initial concentration of phosphorus was 1.29 mmol/l, the initial molar ratio of Ca/P was taken one to three tim...
