BEACH FORMATION OF NON-SEGREGATING TAILINGS

从采矿作业中排出的浓缩尾矿堆积在平坦的地面上，形成一个低矮的圆锥形小山，形成笔直的海滩斜坡。这种堆放尾矿的方法目前正在澳大利亚的九个矿场使用。它性价比高，环境友好。排出的稠化浆料可能会形成更陡峭的坡度，因此需要较少的面积来堆放尾矿。然而，尾矿排放系统的设计必须基于对海滩坡度的准确预测。其目的是通过涉及颗粒力学、流变学以及流量和浓度等工艺参数的实验室实验，提出一种预测海滩坡度的方法。

Thickened tailings from mining operations discharged onto flat ground build into a low conical hill, forming a straight beach slope. This method of stacked tailings disposal is currently employed at nine Australian mine-sites. It is cost effective and environmentally friendly. Discharged thickened pastes can develop steeper slopes, thus requiring less area for the tailings stack. However, a tailing discharge system design must be based on an accurate prediction of the beach slope. The aim is to produce a method of predicting the beach slope angle from laboratory experiments involving particle mechanics, rheology, and process parameters like flowrate and concentration.
