    Yingchun Yang1,*, Liqing Chen1, Xingdong Sun1, Yuguang Mao2

    Journal of Renewable Materials, Vol.10, No.4, pp. 1007-1023, 2022, DOI:10.32604/jrm.2022.017372

    Abstract Herein, micro iron ore tailings (micro-IOTs) were prepared by wet-grinding and applied to improve sulphoaluminate cement (SAC) performance. The physicochemical properties of micro-IOTs were investigated by particle size analysis, XRD, and XPS. The hydrates trait and the hydration mechanism of micro-IOTs-SAC composite were studied by XRD, TGA, MIP, and SEM. The results demonstrated that micro-IOTs with an average grain diameter of 517 nm could be obtained by wet-grinding. The setting time of SAC gradually decreased with increasing micro-IOTs content. By adding 2% micro-IOTs, the compressive strengths of SAC pastes were enhanced about 22% and 10% at 4 h and 28… More >

    Different Effects of Wet and Dry Grinding on the Activation of Iron Ore Tailings

    Yingchun Yang1,*, Liqing Chen1, Yuguang Mao2

    Journal of Renewable Materials, Vol.9, No.12, pp. 2261-2276, 2021, DOI:10.32604/jrm.2021.015793

    Abstract Improving the activity of Iron Ore Tailings (IOTs) to utilize them as a mineral admixture in cement-based minerals is still challenging. In this paper, the wet grinding technology was employed to stimulate the activity of IOTs, and the traditional dry grinding method was used as a reference. The effect of wet grinding on the activation of IOTs was evaluated through ion leaching from an alkaline solution and the reactivity index. Additionally, a detailed comparison between Dry-grinding Iron Ore Tailings (DIOTs) and Wet-grinding Iron Ore Tailings (WIOTs) was made. This comparison was based on particle characteristics, crystal structures, chemical structure, and… More > Graphic Abstract
