FIELD: soil or rock drilling; mining.
SUBSTANCE: invention relates to a method of preparing ore prior to extraction of a useful component. Method consists in fact that ore material is exposed to main and additional pulse magnetic fields, at that direction of action of additional pulsed magnetic field is 30–90° relative to main field action direction. During the period of action of the main magnetic field, an additional magnetic field is applied at least 10 times, wherein the period of action of the additional magnetic field is less than the period of action of the main magnetic field by not less than 100 times. Impulse magnetic field is exposed in inductor at its complete filling with ore.
EFFECT: method provides, in particular, higher extraction of useful component due to reduction of strength characteristics of boundary layer at boundaries of grains of ore and non-metallic phases.
