FIELD: concentration of mineral materials; processing ores, concentrates and industrial wastes, pyrite tailings, for example. ^ SUBSTANCE: proposed method includes preliminary electro-hydraulic treatment of material by pulses at energy of 1-3 J. Treatment is carried out by pulses of nanosecond duration at rate of 106 to 107 pulses per ton of material at pulse power of 108 to 109 W at pulse repetition frequency from 150 to 1000 Hz. ^ EFFECT: reduced power requirements. ^ 1 tbl, 1 ex |
