ABSTRACT:
An electrowinning cell and a cathode for use therein for removal of gold or other precious metals from a solution thereof in a suitable electrolyte. The cathode comprises a perforated steel plate wrapped in layers of woven wire mesh secured thereto. The cathode design is such that the cathode may be cleared of deposited gold sludge by use of an ordinary garden hose spray nozzle without its removal from the cell, making the electrowinning process faster and more economical.
