The comprehensive utilization of tailings is one of the key aspects of green development in the mining industry, and the preparation of geopolymers by tailings holds significant promise. Due to the low reactivity of tailings, thermal-alkali activation can effectively enhance their reactivity, thereby optimizing the performance of geopolymers. To characterize the changes in phase composition and chemical bonds during the activation process, exploring the activation mechanism, X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) were employed. The results indicate that the 7-day compressive strength of thermally-alkali-activated tailings geopolymers can reach up to 15.58 MPa, representing a more than tenfold increase compared to non-activated samples. The compressive strength of the geopolymers improves with the rise of alkali content, calcination temperature and calcination duration. During the thermal-alkali activation process, muscovite in the tailings undergoes structural distortion through group substitution and is converted into an amorphous phase. The alkali content and calcination temperature has a notable impact on the activation effect. The research findings can provide a theoretical foundation for the selection and activation of tailings in geopolymer preparation.

尾矿的综合利用是当前矿山绿色发展的重点之一,而将尾矿制备为地聚物具有广阔的前景。由于尾矿活性较低,热-碱活化能够有效提升其反应活性,优化地聚物性能。采用X射线衍射技术(XRD)和傅里叶变换红外光谱(FTIR)检测,分析了活化过程中物相和化学键的变化,探讨了活化机理。结果表明:热-碱活化的尾矿地聚物7 d强度最高达15.58MPa,相较于未活化时强度提升了10倍以上;随着碱掺量、煅烧温度、煅烧时长的增加,地聚物的抗压强度逐渐提高。热-碱活化过程中,尾矿中的白云母以基团取代而发生结构畸变,转化为无定形相,碱掺量和煅烧温度对活化效果影响显著。研究结果可为尾矿制备地聚物的筛选及活化提供理论参考。

尾矿的综合利用是当前矿山绿色发展的重点之一,而将尾矿制备为地聚物具有广阔的前景。由于尾矿活性较低,热-碱活化能够有效提升其反应活性,优化地聚物性能。采用X射线衍射技术(XRD)和傅里叶变换红外光谱(FTIR)检测,分析了活化过程中物相和化学键的变化,探讨了活化机理。结果表明:热-碱活化的尾矿地聚物7 d强度最高达15.58MPa,相较于未活化时强度提升了10倍以上;随着碱掺量、煅烧温度、煅烧时长的增加,地聚物的抗压强度逐渐提高。热-碱活化过程中,尾矿中的白云母以基团取代而发生结构畸变,转化为无定形相,碱掺量和煅烧温度对活化效果影响显著。研究结果可为尾矿制备地聚物的筛选及活化提供理论参考。

The comprehensive utilization of tailings is one of the key aspects of green development in the mining industry, and the preparation of geopolymers by tailings holds significant promise. Due to the low reactivity of tailings, thermal-alkali activation can effectively enhance their reactivity, thereby optimizing the performance of geopolymers. To characterize the changes in phase composition and chemical bonds during the activation process, exploring the activation mechanism, X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) were employed. The results indicate that the 7-day compressive strength of thermally-alkali-activated tailings geopolymers can reach up to 15.58 MPa, representing a more than tenfold increase compared to non-activated samples. The compressive strength of the geopolymers improves with the rise of alkali content, calcination temperature and calcination duration. During the thermal-alkali activation process, muscovite in the tailings undergoes structural distortion through group substitution and is converted into an amorphous phase. The alkali content and calcination temperature has a notable impact on the activation effect. The research findings can provide a theoretical foundation for the selection and activation of tailings in geopolymer preparation.
