摘要

为实现固废循环利用,降低尾砂和镍渣的固废堆存,开展了镍渣—全尾砂混合骨料配比试验。通过扫描电镜和X射线荧光光谱测定(XRF)方法分析了镍渣和全尾砂的粒级分布和化学成分,利用骨料堆积密实度理论确定了镍渣—尾砂的配比优化范围为4∶6、5∶5和6∶4;考虑料浆的流动性、和易性及充填体强度,最终推荐镍渣—全尾砂的最优配合比为5∶5,料浆的质量浓度为77%~79%,水泥添加量为310 kg/m3;针对镍渣—全尾砂充填,镍渣利用量最高不超过50%,最大质量浓度为79%,对应的剪切应力为112.634 Pa,黏度为0.938 Pa·s。

Abstract

The national sustainable development strategy attaches great importance to ecological and environmental protection issues,and the construction of green mines has become an inevitable trend in the development of mining industry.Solid waste filling is an effective measure to achieve green mines.In order to achieve the recycling of solid waste and reduce the solid waste storage of tailings and nickel slag,the mixed aggregate ratio test of nickel slag-full tailings was carried out to provide technical support for the industrial verification of nickel slag full tailings full solid waste filling.In order to study the optimal mix ratio of nickel slag-tailings paste slurry,the particle size distribution and chemical composition of nickel slag-tailings were analyzed by scanning electron microscopy (SEM),X-ray diffraction (XRF) and other test methods,and the optimal nickel slag-tailings ratio range of 4∶6,5∶5,6∶4 was determined by the aggregate packing density theory.Considering the fluidity,workability and backfill strength of slurry,the optimal mix ratio of nickel slag-total tailings is finally recommended as 5∶5,the mass concentration of slurry is 79%~81%,and the reasonable cement content is 310 kg/m3.For nickel slag-total tailings pumping filling in Jinchuan mine,the maximum utilization of nickel slags is not more than 50%,the maximum mass concentration of nickel slags can be pumped and filled is 81%,the corresponding shear stress is 112.634 Pa,and the viscosity is 0.938 Pa·s.
