Ceramsite filter material has been widely used in water treatment fields such as biological filter, aerated filter and constructed wetland due to its advantages of light weight, many pores and large specific surface area. In order to solve the large-scale storage of mine stripping materials, this paper used the solid waste of sand and gravel aggregate mine stripping materials as main raw material, and added bauxite and limestone to prepare ceramsite filter materials by sintering method. The effects of batch ratio, water consumption, firing conditions and other factors on the performance of ceramsite filter materials were studied, and the sintering mechanism was clarified. The results show that the minerals inside raw materials form strong mineral phases such as anorthite, diopside and corundum. When the mass ratio of stripping material, bauxite and limestone is 7∶4∶1, the sintering temperature is 1 120 ℃ and the holding time is 45 min, the ceramsite filter material with a bulk density of 765.90 kg/m3, a crushing rate of 3.24%, and a porosity of 54.45% is prepared, which provides a new way for high value utilization of mine stripping materials.
