Electrowinning - an overview | ScienceDirect Topics

At the beginning of the plating cycle when the gold solution tenors are high, maximum current is needed to plate the gold. As the gold plates, with removal from the solution phase, the cell resistance will rise and the current will fall. This is in keeping with the need to plate gold at a slower rate in the latter part of the plating cycle.
