A professional who controls equipment to purify copper by electrorefining. Respnsibilities include:

• Signals monorail crane operator to lower impure copper anodes into tank filled with electrolyte.
• Immerses copper starter sheets (cathodes) into tank.
• Passes steel rod between electrodes to break off lumps which might cause short circuit and to verify specified clearance between electrodes.
• Examines, cleans, and tightens electrical connections, using steel wool and handtools.
• Turns on electrical current, and verifies voltage, using voltmeter.
• Measures density of electrolyte, using hydrometer.
• Observes deposition of copper on cathodes, and signals monorail crane operator to remove coated cathodes and depleted anodes from tank after specified time.
• Inspects tanks for defects, such as loose connections, leaks, deteriorated suspension bars and fittings, clogged floats, and drainage connections.
• Repairs or replaces parts, or notifies maintenance department.
• May cover lead sheets with primary coat of copper to make cathodes and be designated Starting-Sheet-Tank Operator.
• May operate equipment that purifies copper through electrolysis without anodes and be designated Electro-Winning Operator.
