| Abstract: |
| High content of copper in cyaniding barren solution of gold industry was treated by ion exchange resin 201×7. The treatment process and kinetics of adsorption were studied. The effects of temperature, pH value, L/S, and time on adsorption were investigated. The results show that ion exchange resin 201×7 can effectively adsorb the copper in cyaniding barren solution. pH value and temperature exert no significant effect on adsorption. The adsorption rate rises with decrease of L/S. The adsorption tends to be saturated in one hour. The adsorption process is controlled by first-order reversible model. |
