Sulfuric Acid Decomposition

В статье обобщены полученные результаты лабораторных исследований и расчета значений термодинамических функций процесса сернокислотного разложения фосфоритного концентрата месторождения Риват. Установлен минералогический состав концентрата рентгенофазовым анализом. Показано, что основной составной частью концентрата является карбонат-фторапатит. В ходе исследования показано, что повышение температуры неблагополучно влияет на сернокислотное разложение концентрата и оно протекает самопроизвольно при комнатной температуре. The article summarizes the results of laboratory studies and calculation of the values of thermodynamic functions of the process of sulfuric acid decomposition of phosphorite concentrate from the Rivat deposit. The mineralogical composition of the concentrate was determined by X-ray phase analysis. It is shown that the main constituent of the concentrate is carbonate - fluorapatite. In the course of the study, it was shown that an increase in temperature adversely affects the sulfuric acid decomposition of the concentrate and it proceeds spontaneously at room temperature.
