Treatment method of phosphogypsum
The invention discloses a treatment method of ardealite. The wet grinding process is adopted to accelerate dissolution of ions such as phosphorus and fluorine in the ardealite, and the additive A is adopted to further accelerate dissolution of harmful impurities in the ardealite; the alkalinity of the additive B is adopted to neutralize the acidity of the ardealite, an alkaline solution environment is constructed, and soluble phosphorus salt is favorably converted into insoluble salt; the adsorbent can be used for further adsorbing ions such as phosphorus and fluorine and organic impurities in the mixed solution, so that through the mechanical action generated by wet grinding, a transfer path for dissolving out harmful impurities, then converting the harmful impurities into an indissolvable state and finally adsorbing the harmful impurities is constructed in the additive A, the additive B and the adsorbent, the immersion of a liquid solvent into a phosphogypsum matrix is promoted, and the phosphogypsum is prepared. And therefore, the removal effect on harmful impurities is improved.
本申请公开了一种磷石膏的处理方法。本申请中采用湿磨工艺加快磷石膏中磷、氟等离子的溶出，采用添加剂A进一步加速磷石膏内有害杂质的溶出；采用添加剂B的碱性中和磷石膏的酸性，构建碱性溶液环境，有利于可溶性磷盐向难溶盐转化；采用吸附剂可以进一步吸附混合溶液中的磷、氟等离子和有机物杂质，由此通过湿磨所产生的机械作用，在添加剂A、添加剂B和吸附剂构建了使有害杂质“先溶出，再转化为难溶态，最后被吸附”的转移途径，促进了液体溶剂向磷石膏母体内的浸入，进而提高了对有害杂质的去除效果。
