electrowinning gold with steel wool cathode

Electrowinning Theory Gold is recovered from pregnant (gold bearing) solution by the process of electrowinning. An electric current is passed through the solution causing solid gold to plate out on steel wool cathodes. Electrowinning is performed in cells, constructed of non-conducting plastic material.

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.

An investigation was undertaken by the Bureau of Mines to develop techniques for removing mercury from cyanide mill solutions by selective electrowinning to reduce the potential hazards. Sixty-five percent of the mercury was selectively electrowon from synthetic-carbon strip solution at applied potentials of 1.00 to 1.50 V when using a mercury-coated platinum or copper-plate cathode.
