Abstract 

The concept of cavitation and flotation technology to separate heterogeneous liquid-phase environments was proposed. It implements the principle of the chemical-technological systems synthesis. The results of approbation of this technology in various industrial processes: sulfuric ore enrichment; intensification of regeneration stage of used absorbent solution from purification process of exhaust gases formed in the calcination furnaces of metatitanic acid paste from SO2; separation of kaolin slurry; extraction of sodium oxalate from liquid wastes of leather industries; separation of the insoluble residue during dissolution of langbeinite ore. High efficiency of the developed technology was shown
