利用配制的矿渣胶凝材料来固化尾矿，并对其进行无侧限抗压强度、重金属的毒性浸出以及BCR重金属形态分布试验。室内试验结果表明，矿渣胶凝材料能有效地降低尾矿中重金属Pb的浸出浓度。当掺入量逐渐增加时，固化效果增强，且可氧化态和残渣态的比率增加，稳定性增强。由此可知，矿渣胶凝材料对尾矿具有良好的固化效果。

Using slag cementing materials to solidify tailings,the unconfined compressive strength,the leachability of heavy metal and the BCR(community bureau of reference)sequential extraction were measured. The results show that the concentrations of heavy metal Pb are effectively reduced by slag cementing materials. The solidifing effect is enhanced,the rate of the residual form and oxidizable form is increased,and the stability is enhanced with the increase of the amount. So the effect of solidifying tailings with slag cementing materials is good.
