The reduction in consumption of energy for disintegration of rock can be achieved by change from compressive mechanical crusing to fragmentation by tension. Of the two techniques for tensile disintegration of rock, instant decompression and electrical disintegration (ED), the latter technique has achieved a stage of development sufficient for its commercial implementation. The ED technique offers reduction in energy consumption, in cost of maintenance, and in the capital cost. The tensile character of the failure ensures the efficient liberation of minerals from the rock matrices. The thermal character of the electrical breakdown of rock provides the possibility for continuous contact between electrodes and rock fragments ensuring the tensile disintegration of solids.
