| 摘 要： | 采用单因素实验分别讨论了十二烷基苯磺酸钠(SDBS)、三聚磷酸钠、硫酸铵等添加剂对四川金河磷矿酸解和硫酸钙结晶的影响.各添加剂的加入量与磷矿质量的百分比分别为十二烷基苯磺酸钠0.15%、三聚磷酸钠1.5%、硫酸铵0.5%时有利于提高P2O5的转化率.这将为人工配矿和低品位磷矿的开发利用提供指导.

| Abstract: | Through the single factor experiments, the influences of sodium dodecyi benzene sulfonate, sodium tripoiyphosphate and the ammonium sulfate on the Sichuan Jinhe phosphate rock decomposition and the shape of calcium sulfate crystallization were discussed. The optimal ratio of each additive to phosphate rock mass was sodium dodecyl benzene sulfonate 0.15%, sodium tripolyphosphate 1.5% and ammonium sulfate 0.5 %. They were favourabie for improving P2O5 conversion rate. |
