Abstract

The results of investigation of the mechanism of destruction of quartz-bearing rocks (ferruginous quartzites) in strong high-gradient pulsed magnetic fields are presented. The model and mechanism of movement of magnetite grains in nonmagnetic quartz matrix under the action of elastic pulse impact and simultaneous strong pulsed magnetic field with the subsequent process of destruction and dispergation accompanied by the development of microcracks along the grain boundaries of minerals are considered. The results of experimental studies of destruction are given.
