Electrowinning - ScienceDirect
2016-1-1 While 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 1000 g/m 2 can accept up to 20 times its weight of gold. As the gold loading increases, however, two changes occur—the available high surface area decreases, and the cathode

electrolysis of gold - Pyrometallurgy: Roasting, Smelting ...
2021-5-22 In this case, gold is deposited on cylindrical steel wool cathode, The anode is stainless steel. Steel wool was used in the first electrowinning cells used in gold mining operations, it is a good unit and leaks are not a problem. It is interesting to indicate that as the gold deposition takes place, the available surface area tends to decrease.
