摘　　要：通过实验室实验和理论分析的方法,对尾矿浓缩进行胶凝材料配比、外加剂选择及配比实验等,最终选择矿渣水泥作为固结胶凝材料(添加量为3%),Na2CO3作为外加剂,添加量取0.1%最佳。研究结果为矿山提供了合理的选择,节约了前期投资成本。Through laboratory experiments and theoretical analysis, cementitious materials ratio test, admixture selection and ratio experiments of tailings thickening are studied in this paper. The results show that the slag cement （additive amount is 3%） and Na2CO3 are selected as cementitious material and admixture respectively. The optimal amount of Na2 CO3 is k3 （0.1%） level. The research results can provide a reasonable choice for the mine and save the upfront cost of investment.
