【摘要】 从煤矸石中提取氧化铝，并用残渣直接煅烧硅酸盐水泥熟料，同时作废气、废液循环，是煤矸石资源开发利用的新工艺。通过对工艺原理的研究，揭示了煤矸石—石灰石—纯碱烧结过程的反应历程及影响氧化铝提取率的因素，分析了残渣直接煅烧水泥熟料的机理和废气、废液循环利用的可能性，实现了资源的合理利用。更多还原

【Abstract】 Extracting alumina from coal refuse, sintering cement clinker directly from residues and circulating waste gas and liquid is a unusual technology for utilization of coal refuse. Based on studies of technical theorem, the coal refuse limestone soda ash sintering reaction process and the influencing factors of alumina extraction ratio are disclosed, and the mechanisms of direct sintering cement clinker and possibility of waste and liquid circulation are analyzed for the purpose of rational utilization of resources.更多还原
