Abstract
The results of modeling the concentration of hydrofluoric acid on the example of processing columbite and loparite concentrates are presented. It is shown that when optimizing the rectification process, it is necessary to use the electrolyte NRTL vapor-liquid equilibrium model and use the total energy consumption going to the separation of the mixture as an optimization criterion. The information about the work on the extraction of anhydrous hydrogen fluoride from hydrofluoric acid is presented.
