Abstract
A method and an apparatus for brushing electrodes such as cathodes used in the electrowinning of zinc and copper wherein opposite surfaces of laterally moving electrodes are cleaned in the area of solution lines with a first pair of stationary, opposed, rotating auxiliary brushes and immediately thereafter the opposite surfaces of stationary electrodes are cleaned below the solution line and between edge sticks with a second pair of vertically moving, opposed, rotating main brushes. The main brushes are pivotally mounted on a pair of vertically-reciprocal carriages having means to center an electrode therebetween.
