Scientific substantiation and development of innovative processes for the extraction of zirconium and rare earth elements in the deep and comprehensive treatment of eudialyte concentrate

Based on a package of modern analysis methods, the influence various acids and energy effects morphology, elemental composition, structural chemical transformations mineral surface, efficiency eudialyte concentrate leaching was studied. The mechanism optimal conditions specific features destruction rock minerals extraction zirconium REE under acids, powerful nanosecond pulses, dielectric barrier discharge, electrochemical processing, mechanochemical activation ultrasound were revealed. formation for dispersion silica gel, depending methods parameters effects, theoretically experimentally substantiated. A combined three-stage circuit nitric acid with ultrasonic treatment suspension, providing 97.1 % 94.5 REE, scientifically substantiated tested. selective deposition
