摘要
煤矸石是大宗固废之一,含有多种有价矿物元素。当前有不少文献综述了国内外煤矸石的利用情况,但未发现专门针对利用煤矸石提取有价元素的概述论文。针对这一现状,在结合国内外学者利用煤矸石提取有价元素的研究基础上,从煤矸石理化特性出发,总结了利用煤矸石提取铝、铁、硅、钛、锂、镓、钒及稀土元素等有价元素的最新技术进展。
Coal gangue is one of the bulk solid wastes that contains a variety of valuable mineral elements.At present,many literature reviews the utilization of coal gangue at home and abroad,however,no overview papers have been found specifically aimed at extracting valuable elements from coal gangue.In response to this situation,this paper summarized the latest technological progress in the extraction of valuable elements such as aluminum,iron,silicon,titanium,lithium,gallium,vanadium and rare earth elements from coal gangue,which startinged from the physical and chemical characteristics of coal gangue,and on the basis of combining the research of domestic and foreign scholars to extract valuable elements from coal gangue.
