英文摘要: |
Since the ammonia-cyanide leaching was developed in 1901, it has been considered as an effective method for selective extraction of gold from the refractory oxidized copper-gold ore. The latest status around the world of gold extraction using the ammonia-cyanide method is systematically reviewed in the present paper, including basic principle of the method, leaching dynamic, solution chemistry, laboratory tests and industrial application. The existing problem is discussed, and future developments are also prospected. |
