The phosphate rock was activated in a hydrothermal reaction kettle by using ammonium sulphate as activator, and the hydrothermal technological conditions were studied. The results showed that the effect of activation was strong when the water-solid ratio was 1:1; ammonium sulphate-phosphate rock ratio was 3:7; hydrothermal time was 12 h; and hydrothermal temperature was 220℃. The available P content in activated phosphate rock increased by 78.2%. The phase change of activation products was studied by X-Ray diffraction, and the phase was changed under the treatment of hydrothermal activation.
Key words： phosphate rock; ammonium sulphate; hydrothermal activation; available P
