| titleOfInvention | The method that a kind of low-grade copper gold dump leaching-charcoal absorption is produced |
| abstract | The present invention relates to the method that a kind of low-grade copper gold dump leaching-charcoal absorption is produced, the high-copper gold loaded carbon employing cyaniding decopper(ing) process portion that low-grade copper gold dump leaching-charcoal absorption process obtains removes the copper in gold loaded carbon, as the spray liquid in dump leaching latter stage after decopper(ing) liquid utilizes absorption lean solution to dilute, decopper(ing) charcoal is sent to High Temperature High Pressure non-cyanide desorption-electrodeposition system process.The present invention has that technical process is simple, less investment, without the need to increasing the advantages such as other former paving material, easily industrializing implementation, production cost are low; High-copper gold loaded carbon, after cyaniding decopper(ing), can improve the golden desorption efficiency of gold loaded carbon, improves the absorption property of regenerated carbon, thus improves the adsorption rate of gold, optimization production technical indicator; Dump leaching is adopted to sink process for copper latter stage, the part copper in decopper(ing) liquid and absorption lean solution can be made again to precipitate in stockyard, and heavy copper can be utilized to react the sodium cyanide Leaching of Gold produced, effectively can control the copper concentration in dump leaching-charcoal adsorption system, production system can be made to be in Recycle mechanism environment all the time. |
