Gold is then leached from the carbon particles by a strong solution of sodium cyanide and sodium hydroxide, and it is recovered from solution by electrowinning directly onto steel wool or by the Merrill-Crowe process. In the latter process, the gold-bearing solution is deoxygenated and passed through a filter-press, where the gold is displaced ...

The quantity of steel wool was estimated by referring to information from the experiment, carried out by DPIM. After assuring that the chemical reaction had stopped, the steel wool containing gold was further separated in the acid treatment stage since steel wool can readily dissolve in sulfuric acid or hydrochloric acid.

Cementation versus eiectrowinning for gold recovery. Because Anglo elution is a batch process a multi-compartment flow-through cell has been designed to treat each batch of eluate. Gold plates onto the steel wool in the normal way but the several banks of steel wool cathodes ensure that the final eluant contains < 1 ppm gold.

The gold can be removed from the carbon by using a strong solution of caustic soda and cyanide, a process known as elution. Gold is then plated out onto steel wool through electrowinning. Gold specific resins can also be used in place of activated carbon, or where selective separation of gold from copper or other dissolved metals is required.

TimBosby Gold Supporting Member. Dec 19, 2004. Omaha, NE, USA. I used some steel wool on a bass recently and taped off the pickups (so I thought). Now, today I discovered tiny bits of steel wool on, around, and in the pickups. I took the pickups out and got as much of it as I could. There wasn't a lot, but what was there was very fine and wispy.
