<p>In the recovery of gold and silver from a solution, e.g. a cyanide wash solution, containing dissolved gold and silver by carbon adsorption in a series of adsorption stages (20, 21, 22, 23, 24, 25), a portion of the loaded carbon is removed partway along the series, and subjected to a stripping operation (26) to recover adsorbed silver. Gold is separately recovered in a second stripping operation (30) on loaded carbon removed from the beginning of the series. Following stripping, the carbon is reactivated (28) and recycled.</p> |
