Abstract
The present invention relates to a system and a method for the concentration of slurry, especially mineral containing slurry. The invention provides a system comprising an electrophoresis unit and a separation unit, where the separation unit comprises a recipient, preferably of half cylindrical form, with adjusted flanks for separating the solid material or cake from the rotating anodes and a sliding carriage suitable for closing the recipient and stripping resting solid material from the flanks into the recipient before the solid material or cake is pressed out of the recipient by a piston.
Claims39
Device for the concentration of a slurry, with a supporting structure for receiving modules therein, the modules comprising
- a. an electrophoresis cell with at least one electrically connected cathode, and at least one electrically connected, rotatable anode disc (50),
- b. separation units adjacent to each anode surface for receiving the cake material, comprising a recipient (40) and a piston (20), wherein the shoulders (30) of the recipient (40) are dimensioned to act as scraping flange for taking off the solid material or cake from the anodes and the piston (20) for pressing the collected material or cake out of the recipient (40),
- c. means for turning the anodes, circulating slurry in and out of the electrophoresis cell, and applying voltage to the electrodes.
