Abstract

A technology for increasing the capacity of tailing site for metal mine features that the dam of the said tailing site is further built upward vertically along the axis of upper sub-dam and a hydraulic cyclone is used to discharge the coarse particles outside the damp and stack the fine particles inside the dam. Its advantages include high effect, and high safety.

Description

[0001] Field

[0002] The invention relates to the field of tailings stacking, in particular to a process for increasing the height and expanding the capacity of metal ore tailings storage. Background technique

[0003] At present, most of the domestic metal ore tailings pools are in the middle and late stages of storage capacity and service life. In order to maintain the continuous production of mines, they are all looking for the best solution for the later storage of tailings to solve the problem of continuous storage of tailings. The solution: one is to build a new tailings pond, and the other is to transform the existing tailings pond. If a new tailings pond is built, there will be problems such as large investment, difficult land acquisition, large environmental impact, and long construction period; Dam, the sub-dam body contains multi-layered clay interlayers, the dam body has a high soaking line, low structural strength, and poor stability of the dam body. If you cont...
