溪口砂金矿淋渗法处理选矿污水的研究

Study on treating waste water of mineral processing by percolation method in Xi-Kou Alluvial Gold Mine

淋渗法是砂矿采选中利用尾砂处理污水的方法。污水流入尾砂砾集合体中，大量微细分散的悬浮物充填在该集合体中，水经其孔隙渗透到汇水区。本文利用水力学原理分析了淋渗法渗透水的运动规律，提出了处理能力与受水面积等参数的确定方法，并介绍了淋渗法的基本工艺。

Percolation method is the method which utilize tailing to treat waste water in the mining and processing of alluvial gold ores. Waste water flow into aggregates of tailing gravel bringing about a great quantity of fine and dispersive suspended matters to fill in these aggregates. Water percolate into catchment throngh cavities of the aggregates.Utilizing prineiple of hydraulics, this paper makes an analysis of motion regularity of water percolation and from the analysis derives a method to determine the parameters as treatment capacity of waste water,water intake area etc.The basic technology of percolation method is introduced in this paper.
