An improved apparatus and process for electrolytically producing a particulate crystalline metal product having limited adherence to the surface of a cathode, comprising a vertically elongated cathode, at least one vertically elongated anode spaced from said cathode, a vertically elongated permeable diaphragm disposed between said anode and cathode having a mesh member disposed adjacent to the surface of said diaphragm nearest said cathode, agitating said anode to substantially reduce the polarization voltage of said anode, and agitating said cathode to dislodge a portion of said crystalline product from said cathode by engaging said product with said mesh member.

Electrolytic cell

In an electrolysis system capable of producing particulate crystalline product having limited adherence to the cathodes, a process and apparatus for the continuous recovery of said product directly from the electrolytic cell tank substantially uncontaminated by adhering electrolyte comprising the agitation of the electrolyte to effectively influence and contribute to the control of the crystalline product size and density as well as the structural competence of the dendrites and to cause said product to separate from the cathodes, the collection of the particulate crystalline product on a conveyor transport system located in the bottom part of the electrolytic cell tank, the continuous removal of the particulate crystalline product from the electrolytic cell tank by means of the conveyor transport system, and the transportation of the crystalline particulate product through a washing zone prior to its removal from the electrolytic cell tank to substantially displace the electrolyte liquor from the particulate crystalline product.
