Title:

METHOD OF SUPERIMPOSING ALTERNATING CURRENT ON DIRECT CURRENT IN ELECTROLYTIC METHODS

Document Type and Number:

WIPO Patent Application WO/2015/075634

Kind Code:

A3

Abstract:

The invention concerns a method of superimposing alternating current on the direct current fed to a group of electrolytic cells for the electrowinning or electrorefining of copper and other products. The invention is characterized by: (a) the incorporation of an inductor which is connected between the terminals of the intermediate cells of the electrolytic cell group and the functions of which are to act as an alternating current filter and as a means of conducting direct current; (b) the incorporation of a capacitor which is connected in parallel to the original direct current source and the functions of which are to act as a means of conducting alternating current and as a direct current filter; and (c) the incorporation of an alternating current source which is connected at the terminals of an inductor disposed at the central point of the electrolytic cell group.
