Abstract：The comprehensive utilization of phosphogypsum is of great significance to the sustainable development of phos-
phor-chemical enterprise and the eco-environmental protection of the Yangtze River ，the phosphogypsum
contains a small amount of phosphorus，fluorine，organic compounds，and so harmful impurities impact its application
performance，which can′t be used ，the distribution and removal of water-soluble phosphorus and water-soluble flu-
orine in phosphogypsum from a company in Anning were studied by lime neutralization，water washing and re-
sults showed that the water-soluble phosphorus and water-soluble fluorine in phosphogypsum could be removed effectively by
gypsum mixing，adding lime and mother solution cyclic utilization removal rates of them were % and
% respectively，and their contents were % and % separately，which could meet the limit requirements of sec-
ondary indicators in GB/T 23456—2018《phosphogypsum》 water-soluble phosphorus and water-soluble fluorine
could also be removed effecti
