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.

First claim

The invention claimed is:

1. A separation unit for use with a device for the concentration of slurry, the separation unit comprising a recipient and a piston adapted to the recipient form, wherein the recipient has shoulders dimensioned to act as scraping flanges for cake material, the piston is dimensioned for pressing 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, the recipient has a half cylindrical or half rectangular form, and the separation unit has a pneumatic cylinder that drives the piston pneumatically.

2. The separation unit according to claim 1 , wherein the separation unit is made of poly-tetra-fluoroethylene.
