| Abstract: |
| Coconut shell activated carbon has been widely used in CIP process. Adsorption capacity and adsorption rate is index of the activity of activated carbon. Strength is the main property of activated carbon in the process of CIP to resist abrasion. The experimental results taking activated carbon from a gold smelter show as follows: Increases as the amount of upload gold activated carbon, the adsorption activity will decline, and finally reach adsorption equilibrium. Activated carbon as long as the pretreatment grinding angle before adsorption, its strength in the adsorbed stage change is not obvious, even if gold loads increase, its abrasion in every tank is remain stable. |
