研究了机械活化反应器中，温度、溶出原液α＿Ｋ、溶出时间及液固比等因素对平果铝土矿溶出率的影响．在２２５℃，溶出原液α＿Ｋ３．２，Ｌ／Ｓ２．５，溶出２ｈ的条件下，Ａｌ＿２Ｏ＿３的溶出率达９６．６０％，比相同条件下的高压釜溶出率高１８％；动力学研究表明，在１３８～１７６℃，范围内，试验结果能很好地模拟动力学模型１－（１－Ｘ）￣（１／３）＝ｋ＿ａｔ，测得其表观活化能为７２．６４ｋＪ／ｍｏｌ，溶出过程属化学反应控制．研究结果表明，机械活化可明显改善一水硬铝石的溶出性能，强化其溶出过程，提高其溶出率。
The effects of temperature, dissolved solution α_K, dissolution time and liquid-solid ratio on the dissolution rate of bilobal were studied in the mechanical activated reactor. The dissolution rate of Al_2O_3 was 96.60% at 225 ℃ when the eluents of α_K3.2, L / S2.5 and 2h were eluted, which was 18% higher than that of the autoclave under the same conditions. Kinetic studies showed that, The kinetic model 1- (1-X) ¯ (1/3) = k_at can be well simulated in the range of 138 ~ 176 ℃. The apparent activation energy is 72.64kJ / mol and the dissolution Process is a chemical reaction control. The results show that mechanical activation can significantly improve digestion of diaspore dissolution, strengthening the dissolution process and improve the dissolution rate.
