【Abstract】 The influence of crystallization temperature, reaction time, stirring intensity,and crystal modifier on co-crystallized phosphorus content in phosphogypsum was studied emphatically. Under the experimental condition, the co-crystallized phosphorus content was reduced by about 70%, and it was 0.5%（P₂O₅） when the concentration of phosphoric acid solution was 32%（P₂O₅）.更多还原
