煤矸石制取含铝产品的研究进展

Research of Making Aluminium Product from Coal Refuse

综述了利用煤矸石制取含铝产品在煤矸石提质、浸取、除铁和高附加值利用矸石制取无机高分子絮凝剂和纳米级Al2 O3 的相关工艺及研究进展 ;并指出在今后的研究工作中 ,必须注意避免二次污染问题 ,而且要增加对Si、Al同时加以利用的研究。

In the process of making aluminium product from Coal Refuse, related process and development such as extraction, lixiviation,deferrizing and producing inorganic macromolecule flocculant and nanometer Al\-2O\-3 are discussed.It is pointed out that during the coming research work, more attentions should be paid to re-polluting and the research of utilizing the si and al at the same time.
