| Abstract: | The kaoline having a high mole ratio of SiO2 to A12O3 is suggested as the raw material for processing white carbon. In this process, calcining activation and acid leaching are often combined together. In this investigation, the mono- factor experiment design method is employed to give the optimum technical conditions. From the experimental results, it could be seen that the optimum calcining temperature, calcining time, leaching temperature, leaching time, and concentration of hydrochloric acid are 700 ℃, 1h, 90 ℃, 1 h and 20 % respectively. |
