Possibilities of high-pulse processing of thin-deposited mineral complexes are shown, which allows to obtain stable increase of extraction of valuable components (gold by 30-80%, silver на 20-50%) at reduction of energy consumption and decrease in the cost price of finished products during enrichment of refractory gold-bearing ores and enrichment products. The results of theoretical and experimental investigations of mechanisms of non-thermal impact of powerful electromagnetic pulses with short (nanosecond) front and duration at electric field strength of 107V/m on natural mineral media of complex material composition are presented.
