DetailsPulsed electrowinning at 2.0 V with periods ranging from 1 ms to 10,000 ms was successful in lowering the Ag and Au concentrations of the solution below 1 µg/mL in the most favorable circumstances. Pulsed electrowinning at 2.5 V was also effective in removing Ag and Au from solution, but apparently offered no advantage over a 2.0 V pulse.
DetailsWhile not exhaustive, the following aspects are considered key to the design and operation of electrowinning circuits in gold plants. 5.1. Gold to steel-wool loading ratio. Experience has shown that a cathode wound to a density of approximately 1,000 g/m 2 can accept up to 20 times its weight of gold. As the gold loading increases, however, …
DetailsNikkelverk's electrowinning plant produces nickel "crowns" as well as full cathode plates. They are used by the nickel plating industry. They are produced by masking titanium mother blanks with polymer—except for unmasked circles where nickel electrodeposition can occur. In nickel chloride electrowinning, coated titanium anodes are used.
