Modern technologies in the system of regeneration and purification of boron concentrate

Abstract

The analysis of the efficiency of the technological chain of a typical installation (device) SVO-6 is performed. Characteristic drawbacks, inherent in combined “evaporation-ion-exchange filtration” systems conditional to the properties of boric acid and the displacement of ammonia by ammonia with rapid depletion of anionite filters, are revealed. The possibility of replacing the existing scheme with high-tech baromembrane technology based on modern boroselective membranes is shown.
