The technology of water washing can remove all above-mentioned harmful impurities except of P〓O〓 in crystal lattice. However, the feasibility of water washing technology may rely on the ability in investment as the initially required investment size is big. Also, this technology may cause a secondary pollution as the process generates large amount of waste water. Organic matters can be removed by a floating technology. Lime may be used as a neutralizing agent which transforms watersoluble P〓O〓, F〓 into salts of low solubility. Grinding can improve the crystal morphology and the gradings of PG. A combined technology of neutralization with grinding may have the advantages of both.
水洗可除去除共晶P〓O〓以外的所有杂质，但存在一次性投资大、工艺复杂、污水排放造成二次污染等问题；浮选可除去磷石膏中的有机物；石灰中和使有害态的可溶磷、氟转化为惰性的难溶盐；适当的球磨可有效改善磷石膏的颗粒形貌与级配；筛分可除去有害杂质含量特别高的部分，提高磷石膏品质；球磨与石灰中和结合的预处理工艺，既消除了主要有害杂质的影响，又改善了磷石膏颗粒结构与级配。

fines：细小纤维
造纸过程一般是以纸浆的筛分组分来区别长纤维(fibres)和细小纤维(fines). 一般来纸浆细小纤维还有初级细小纤维(primary fines)和二次细小纤维(secondary fines)从纤维形状来看,木材纸浆细小纤维可以分为纤丝状细小纤维(fibril fines)和薄片状细小纤维(flake fines)两种.
