Polypropylene cathode baskets retain the stainless steel stocking or steel wool so as to avoid any opportunity for shorting between the cathode stocking/wool and the anode mesh. Anodes & cathodes can be readily accessed and removed.
Cathode frame support either wrapping of mild steel or stainless steel wool for plating and sludging operations respectively, or alternatively accommodate pre-manufactured. Electrowinning and Smelting Resource Book. Electrowinning and smelting are the final stages of gold production.
A steel wool cathode becomes coated with gold as electricity is passed through the solution in an electrolytic cell. Excess steel wool is dissolved in hydrochloric acid and the gold passes to a smelter. Smelting: Smelting involves heating the crude gold until it melts, at which point most impurities float to the surface as a slag.
The gold is extracted from the cyanide solution using activated carbon. The gold is removed from the activated carbon into a solution. This solution undergoes electrowinning to deposit the gold onto steel wool, which is then smelted into an impure gold bar. These impure bars are sent to the Rand Refinery for final treatment to produce pure gold.
The carbon used in the process is recycled and an electric current is passed through the new solution, depositing the gold on a steel wool cathode. The gold laden cathode is treated with hydrochloric acid to dissolve any residual steel and the gold sludge is filtered and dried, ready for smelting.
stainless steel cylinders, where the outer one is the anode and the polished inner one is the cathode. The latter may be rotated periodically so that electrodeposited gold particles, which are loosely adherent to the cathode surface, are scraped off by means of a fixed rubber scraper, and drop downwards under gravity. The action of eluate ...

A hydrometallurgical process for treating copper feed materials containing gold and/or silver by simultaneously leaching copper, gold and/or silver into an aqueous cyanide solution, recovering copper in metallic form by electrowinning and regenerating cyanide ions is provided, wherein high current efficiencies are achieved at high current densities and at low copper concentrations.
for cyanide leaching. Gold is collected on carbon and electrowon on steel wool. The gold-laden steel wool is smelted on-site to produce dore' gold bars. The following is a description of management practices of small volume wastes generated at this mine. As part of the gold/steel wool smelting process, sodium nitrate, silica, and
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.
The gold-rich eluate is fed into an electrowinning circuit where gold and other metals are plated onto cathodes of steel wool. The loaded steel wool is pretreated by calcination before mixing with fluxes and melting. Finally, the melt is poured into a cascade of molds where gold is separated from the slag to gold .

Gold room operations can be as simple as a single electrowinning cell and eluate tank, drying oven and smelting furnace. Or they can incorporate gravity-concentrate tabling, separate concentrate leaching, multiple electrowinning cells, cell-mud handling and filtration, and large-scale smelting operations.

Stainless steel wool was considered, but gold recovery from the cathodes presented some difficulty. The best results were obtained with a cathode constructed from stainless steel mesh and only these results are discussed in more detail below. 5.2.1.
Another thing about mercury: the article states that it's removed from electrowinning cathode material or Merill-Krowe precipitates by retorting. I'm not aware of any examples of retorting the steel wool cathodes prior to smelting. Retorting was the process used when mercury was intentionally used to recover gold by amalgamation.
The smelting step of refining consists of heating the loaded steel wool to melt the gold at 1300°C, with fluxes of silica, feldspar, and borax, to remove impurities. Complete separation occurs within 1.5 hours, at which point the slag is poured off and the molten gold is poured into anode casts and cooled. The anodes are approximately 99%
