PROCESS FOR THE RECOVERY OF GOLD FROM CARBONACEOUS ORES

摘要

PROCESS FOR THE RECOVERY OF GOLD FROM CARBONACEOUS ORES The recovery of gold from refractory carbonaceous gold-containing ores by cyanidation techniques is improved by subjecting an oxidized slurry of this type of ores to simultaneous cyanidation and countercurrent granular activated carbon adsorption in two or more stages. The gold transfers to the carbon and may be separated from it by conventional methods. S P E C I F I C A T I O N
