摘要
用盐酸分解磷矿粉所得之酸解液为很难过滤的多分散体系。我们用聚丙烯酰胺(PPA)、明矾、聚合氯化铝对其进行了絮凝实验,得到了较为理想的絮凝剂配方。
The slurry which was produced by the decomposition of powdery phosphate rock with hydrochlorid acid is a polydisperse system which has a bad filterability. The slurry was flocculated by P.P.A, alum and P.C.A respectively and a good dispensation of flocculate agent was obtained.
