尾矿特性对充填工艺及胶结强度的影响

尾矿胶结充填的质量与料浆浓度和成分有关,因此对尾矿特性进行深入研究,实现低成本制备高浓度尾矿、确定合理输送浓度有着非常重要的意义.通过对不同特性和浓度尾矿的研究,即对尾矿成分、粒径、级配、稠度、粘度、孔隙压力、密度、孔隙率、悬浮物组成等的研究,解决尾矿制备过程中进料、沉降、浓缩、溢流澄清、去除有害物质中的问题,从而确定高浓度尾矿的输送方法、采场接顶方法、脱水方式等,创建合理的矿山充填系统.

Influence of tailings' behavior on the filling technology and the cementing strength

In the process of tailings filling,the quality of consolidated backfilling is affected by slurry concentration and composition, and therefore,it is important to study the tailings behavior for the preparation of high thickness tailings by low-cost,determination of transportation slurry thickness.Different behavior and thickness of tailings were studied,including the tailings composition, particle size,size distribution,consistency,viscosity,pore pressure,density,porosity,composition of suspended matter and ...
