• 2) Switches on current and starts circulation pumps to remove copper from solution and deposit it onto cathode.

• 3) Pumps solution into high-voltage tank system to deposit arsenic on cathodes.

• 4) Pumps electrolyte from high-voltage tanks into evaporators that concentrate solution to specified specific gravity.

• 5) Turns valves to drain condensed solution into settling tanks and to recover acid after nickel sulfate has settled.
