| 摘 要： | 天然的高岭石型煤矸石性质稳定,不进行活化处理难以直接提取其中的铝资源。实验对高温煅烧和机械球磨两种提高高岭石反应活性的方法进行了研究。适宜的煅烧或球磨使煤矸石活性显著提高,Al的浸取率分别达到75.31%和88.17%;两种活化方式的搭配使用更有利于提高煤矸石的反应活性,且先球磨后煅烧的煤矸石活性最高。

| Abstract: | Raw kaolinite-coal-gangue is very stable and difficult to leach Al straightly without activation.Two methods,i.e high-temperature calcinations and mechanically ball-milling for kaolinite activation are systemically investigated.Results show that the reactivity of kaolinite-coal-gangue can be markedly (enhanced) by high-temperature calcination or mechanically ball-milling,and the maximum leaching ratio of Al is 75.31% and 88.17%,respectively.Application of calcining and mechanical milling together benefits the activation of coal gangue,and the best effect is achieved by ball-milling followed by calcining. |

| Keywords: | coal-gangue high temperature calcining mechanically ball milling kaolinite activity |
