【摘要】：为优化膏体充填骨料粒级级配,提出了基于选矿流程的尾矿优选组合膏体充填工艺技术。该技术统筹考虑充填方案、充填成本等因素,基于选矿流程多环节生产尾矿的条件,将不同级配、化学成分合理的尾矿按照一定的比例进行混合,制备出级配连续的混合尾矿。通过开展尾矿基础参数测试、沉降试验、析水试验、流动性试验研究,确定了基于选矿流程的充填技术工艺优化方案,并开展了工业现场验证。基于尾矿级配优化的膏体充填技术科学可行,具有广泛的适用性,是一种先进的矿山充填技术。
[Abstract]:In order to optimize the gradation of paste filling aggregate, the technology of tailings optimal separation and combination paste filling based on mineral processing process was put forward.Considering the filling scheme, filling cost and other factors as a whole, based on the conditions of multi-link production of tailings in the process of mineral processing, the tailings with different gradation and reasonable chemical composition are mixed in a certain proportion to prepare the mixed tailings with continuous gradation.Through the test of tailings foundation parameters, sedimentation test, water evolution test and fluidity test, the optimization scheme of filling technology based on mineral dressing process was determined, and the industrial field verification was carried out.Paste filling technology based on tailings gradation optimization is scientific and feasible and has wide applicability. It is an advanced filling technology in mines.
