13 Jul: Upgrade of Gold Recovery from Refractory Carbonaceous Gold Ores using Phanerochaete chrysosporium – Prof Grace Ofori-Sarpong
Gold ores consist of those that are easy to treat (free-milling) and others difficult to treat (refractory). Cyanide dissolution of gold from refractory carbonaceous ores has attendant serious challenges as the contained natural Carbonaceous Matter (CM) preg-robs dissolved gold leading to a decrease in overall gold recovery, a phenomenon termed preg-robbing. The CM behaves similarly to activated carbon, and thus has strong affinity for the dissolved gold ions (Au(CN)2).
