With the development of industry of phosphate fertilisers, questions of use of phosphogypsum are becoming more important for several reasons: 1-transportation of phosphogypsum dumps and stored in them is associated with higher capital investment and operating costs; capital investments according to the data reported by enterprises constitute about 12% of the average unit cost of construction of its own plant EPA (abroad-11%) and significantly increased during the transition to гидротранспортирование phosphogypsum; operating costs according to the make up of the average 17.6% of the average cost price of processing of raw materials. The cost of destruction of phosphogypsum vary depending on the method of removal and reach US $ 27 per 1 t of P2O5.
Thus, In the present article contains a study of interaction СаSO4 c H2 obtaining Cao. The method of parametric optimization using the multipurpose software complex «Astra» is shown that the total interaction СаSO4 c H2 occurs at Т≥ 1400К and the number of moles of H2 from 0.5 to 2.0.
