ABSTRACT:
A fluid bed electrolysis process is provided for the recovery of nickel from nickel-containing solution, e.g., leach solution, in which a fluid bed of substantially pure nickel particles or pellets of size ranging from about 150 to 2000 microns is employed, the fluid bed being preferably formed of reduced nickel oxide, such as hydrogen-reduced nickel oxide.
