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.
Claims21
A device for the concentration of a slurry comprising a mineral, with a supporting structure including modules received therein, the modules comprising:
- a. an electrophoresis cell with at least one electrically connected cathode, and at least one electrically connected, rotatable anode disc,
- b. a separation unit adjacent to each anode surface for receiving a cake material of mineral, comprising a recipient and a piston adapted to the recipient form, wherein the recipient has shoulders dimensioned to act as scraping flanges for taking off the cake material from each anode, the piston is dimensioned for pressing the cake material out of the recipient, the separation unit has a sliding carriage with a cover for closing the recipient and collecting residual cake material from the shoulders into the recipient while closing it, and the recipient has a half cylindrical form.
