The copper industry in the United States has two main segments: producers-mining, smelting, refining companies; and fabricators-wire mills, brass mills, foundries, powder plants. The end products of the producers, the most important of which are refined cathode copper and wire rod, are sold almost entirely to the copper fabricators.

In copper electro-refining the copper anode and copper deposit on the cathode leach very slowly in electrolyte, and do not set up a galvanic couple. In electrowinning however the copper on the cathode and the lead anode do set up a reverse voltage. The resultant reverse current flow can have dramatic impacts on electrodes and copper product:
