| Abstract: | According to the basic theory of the activated carbon adsorption,this paper suggests a new technology of cyanic-free desorption.Using the principle of the vapor reflux,the water/reagent E is selected as a desorption reagent which results in the reduction of absorption time to 2 hours.The percen- tage desorption makes a break-through on domestic and international level at present.The quantities of residual gold on the carbon is 30g/t. |
