在保持某选厂原有工艺流程及设备不变的条件下，对含铜浮选尾矿氰化吸附进行试验研究。通过不同炭密度条件下的标准炭浸试验结果，绘制吸附平衡等温线计算理论底炭量。通过炭浸吸附试验，模拟因回水方式导致溶液中不同铜浓度对金、铜浸出及吸附的影响。结果表明，只要溶液中铜的含量不太高，同时能保持足够的自由CN-，则即使不将吸附贫液除铜，使用活性炭吸附也可以获得良好的金吸附结果。高铜载金炭先脱除铜后再进入解吸、电积工序。研究结果为工业应用提供了试验依据。

While maintaining the original process and equipment on the same conditions in a dressing plant,the cyanide-adsorption test researching of the copper flotation tailings was conducted.The equilibrium adsorption isotherm was plotted and the theoretical base carbon content was calculated by using the result of the standard carbon leaching test which in the different condition of the carbon density.Meanwhile,through the carbon leaching-adsorption test,it was simulated for the impact on gold,copper leaching and adsorption of the different copper concentrations in the solution as the different return water mode.The results show that gold adsorption results can be obtained by the activated carbon adsorption,even though not excluding the copper from the poor liquid adsorption as long as the content of copper in solution is not too high,and the free CN- maintain adequate. The process was proposed which removed copper firstly and then conducted desorption and electrowinning for the gold loaded carbon with high copper content.This finding provides an experimental basis for industrial applications.
