Abstract

A hanger bar (30) for use in electrowinning or electrorefining comprises two stainless steel strips (12) which are welded to a row of stainless steel blocks (34) so that the blocks are between the two strips. The blocks and strips are then sand blasted and a layer of copper is deposited onto the strip and blocks.
