| Abstract: | In this paper,the leaching behaviour of alumina from kaolin by hydrochloric acid was described.The effects of calcinating temperature,hydrochloric acid concentration,molar ratio between hydrochloric acid and alumina,leaching time and additives on leaching rate of alumina were investigated.It was found that leaching rate of alumina can be reached to 89% in following conditions:calcinating temperature of 700℃,hydrochloric acid concentration of 30%,molar ratio between hydrochloric acid and alumina of 6,and leaching time of 2h.Leaching time could be reduced by using additives. |
