• gold ore. The bubbles are generated by shock loading of the liquid heated to the boiling temperature. Possibilities of cavitation separation of nano- and microscale monomineral fractions from polymineral nano- and microparticles and of the use of cavitation for beneficiation are demonstrated

• disintegration; gold ore; nano- and microparticles; polymineral and monomineral fractions; Introduction At present, significant attention is being paid to the study of properties and processes of formation of mineral nano- and microsize particles [1][2]. The investigation of nanosize structures in nature can

• result of the interaction of particles with collapsing cavitation bubbles was shown for the minerals most abundant in gold ore. This disintegration mechanism is important because the availability of high-grade deposits in the process of mining and production of noble metals is decreasing. This demands
