采用“旋流器-浓密机”分级浓缩流程对某铁矿尾矿进行了半工业浓缩试验。结果表明,采用φ125mm旋流器和φ2000mm膏体浓密机组成的分级浓缩系统,尾矿浓度由19.62%增加至54.32%,达到了全尾矿高效浓缩的技术要求,为尾矿充填采空区奠定了基础。
A semi-industrial concentration test was carried out on a certain iron ore tailing by using “Cyclone-thickener” fractional concentration process. The results showed that the concentration of tailings increased from 19.62% to 54.32% using the φ125mm cyclone and φ2000mm paste thickener, which met the technical requirements for efficient tailing of tailings and laid the foundation for the tailings filling goaf The foundation.
