Abstract: According to development idea on circular economy and clean production to exploiting mineral resources,the present output and harm of producing on mine tailings were briefly reviewed.Tailings stockpiling have terrible effects on the expropriation of land,the destruction of the ecological environment,causing air pollution,easy to produce the safety accidents,etc.Therefore,two approaches of comprehensive utilization on tailings,i.e.,recycling of useful components and bulk of consumption were introduced.On the basis of descriptions on the technical features of tailings,related properties of autoclaved aerated concrete(AAC)with large amount of tailings utilization,significant in energy saving,thermal insulation,light weight,easy processing,aseismatic performance were indicated respectively,The technical status of utilizing iron tailings,copper tailings,gold tailings and other mine tailings to produce autoclaved aerated concrete was summarized intensively after the preparation mechanism of autoclaved aerated concrete and the characterization of autoclaved aerated concrete product were presented in turn.Combining with production of autoclaved aerated concrete and application practice,Focus of attention of utilizing tailings to producing autoclaved aerated concrete such as mine tailing granularity on the adaptability of building materials,effects on activated lime quality and raw calcium minerals,attention to the scientific test and talent training,strengthening the study on mechanical properties of tailings building materials products,etc.is raised in the end.
