Separating gravel- and cement phases from contaminated material, comprises introducing contaminated material into container containing liquid, first and second electrode, and generating voltage pulse between electrodes to comminute material

摘要

Separating the gravel- and cement phases from contaminated material, comprises: introducing the contaminated material into a container which contains a liquid, and at least a first and a second electrode; and generating at least one voltage pulse between the electrodes such that the material is comminuted.
