摘要：

煤矸石是采煤和洗煤过程中排放的固体废渣，它是在成煤过程中与煤层伴生的一种含碳量较低、比煤坚硬的黑灰色岩石。煤矸石是我国排放量最大的工业废渣之一。本文综述了利用煤矸石制备铝基化工原料、建筑材料和多孔陶瓷等高值材料的最新研究进展，并展望了其应用发展前景。

Abstract:

Coal gangue is the solid waste discharged in the processes of coal mining and coal washing,and it is a kind of black gray rock with lower carbon content and harder than coal in the process of coal forming.Coal gangue is one of the largest industrial wastes in China.In this paper,the research progress of high value materials such as aluminum-based chemical raw materials,building materials and porous ceramics using coal gangue is reviewed,and the prospect of its application development is forecasted.

Key words: Coal gangue, High value utilization, High value materials, Research progress
