Use of cationic surfactants in the cyanidation of refractory carbonaceous ores for recovery of metals |
| abstract |
A process for recovery of precious metals from ores or concentrates containing refractory carbonaceous material by cyanidation leaching. The process involves addition to the ores or concentrates at least one cationic surfactant before or during the addition of cyanide-containing solution. The agent enables the recovery of precious metals by cyanidation from high preg- robbing carbonaceous ores and improves the recovery of precious metals by cyanidation from medium to low preg-robbing carbonaceous ores. The agent also prevents froth and foaming formation during the cyanidation process. |
