摘要
以丹东爱阳镇凤煤煤矿未经焙烧的煤矸石为研究对象,采用XRF,XRD,SEM,TG,TPO-MS等分析方法深入研究煤矸石的性质,并考察了球磨机自转公转转数,机械力化学活化时间,浸出用碱量,有无助磨剂等试验条件对硅浸出率的影响。结果表明:采用XQM2-2L型球磨机活化样品时,自转公转转数对硅浸出率有显著影响;延长机械力化学活化的时间,增加浸出用碱量,或采用助磨剂均可以提高硅的浸出率。
The coal gangue was characterized by XRF, XRD, SEM, TG, TPO-MS methods. Effects of activation conditions on the extraction percent of Si, such as rotation rate, mechanochemistry activation time, alkali quantity, with or without grinding aids were examined by XQM2-2L planetary activator. The results indicate that the extraction percent of Si could be increased with the increasing of activation time or the quantity of KOH, or activation with grinding aids.
