The Electropulse Disintegration of the Au-sulphid (Darasun), Au-Ag (Chukotka) and Au-conglomerate (Witwatersrand) ores were investigated. The working principle of the laboratory unit is based on the using electro hydrodinamic effects accompanied by the spark discharge withing the solid and liquid. When the electric discharge passing through the ore the low temperature plasma originates in the disharge channel, which initiates impact waves by the which aim wedged out and breaking pressures are appeared. The dischrge developing channel crosses along the electric field high pressure zones, which originated close to the heterogeneities which electric charactericts differs from the rock-originated matrix, i.e. on the mineral intergrowthes lorders. Therefore selective breaking has taken place.
