Abstract
A fluid bed electrolysis system and process are provided for efficiently removing electroplatable metal ions from an electrolyte, the system utilizing a cell having an axially disposed anode surrounded by a cathode, the anode being partitioned from the cathode by a porous diaphragm. The porous diaphragm defines an anode chamber surrounded by an annular cathode chamber, the annular cathode chamber being adapted to support a fluidizable cathode bed of electrically conductive particulate material, the system having electrolyte circulating means for recirculating electrolyte through said cell and for maintaining said electrically conductive particulate material in an electrochemically active fluidized state, including means for disengaging gas bubbles from said circulated solution formed during electrolysis.
