摘要
采用四川清平磷矿，研究了硫磷混酸分解磷矿第２阶段的酸解反应特性。实验结果表明扩散对过程影响严重，在此基础上提出了强化第２阶段反应过程的措施。
The performance of the second stage acidulation process of Qin Ping phosphate rock with mixed acid of sulphuric acid and phosphoric acid was studied. The results of experments indicate that diffusion is the controling step of the acidulation process. On the basis of the study, a method of optimization for the second stage acidulation process was presented.
