摘要
The second stage of the process of preparation of phosphoric acid by the dihydrate-hemihydrate method from low-grade phosphorites is studied. Experiments on the kinetics of the hemihydrate stage are conducted. A mathematical model based on the process kinetics is developed. The hemihydrate stage of phosphoric acid preparation is optimized.
