Abstract
The first stage for the process of phosphoric acid production by dihydrate- hemihydrate method from poor phosphorites was investigated. Experiments on the dihydrate stage kinetics were carried out. Mathematical model was developed based on the process kinetics. The dihydrate stage of phosphoric acid production was optimized. A software package was developed to determine sulfuric acid dissolution efficiency and the solid phase crystallization under different temperatures and concentration conditions.
