PCT No. PCT/EP90/00292 Sec. 371 Date Nov. 6, 1992 Sec. 102(e) Date Nov. 6, 1991 PCT Filed Feb. 21, 1990 PCT Pub. No. WO90/10736 PCT Pub. Date Sep. 20, 1990.The bulk material is transportable in an electrolyte in the conveying trough of a vibrator conveyor. The perforated conveying trough constitutes one of the two electrodes. According to the invention, the polarity of the conveying trough (21) and of the other electrodes (36 to 39) is reversible. The conveying trough (21) and the other electrodes (36 to 39) may be fastened preferably on common supporting stringpieces (22 to 27), which serve at the same time as power lead for one of the two electrodes and are connected with the central pipe (2). With this design the life of the other electrodes (36 to 39) is lengthened.
