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.
