Introducing a bypass-backup connection system for current mode copper electrowinning intercell bars

Abstract

The proposed system is suitable for current mode segmented intercell bars. These bars are immune to short circuits but sensitive to open circuits and dirt contacts. This new system adds segmented sidebars to interconnect in groups the otherwise electrically insulated cathode and anode hanger ends. The combination of a segmented main bar with these sidebars offers immunity to short circuits, open circuits and bypasses dirt contacts. Moreover, exhibits the best current balance ever reported ensuring high energy efficiency.
