A channel body structure for in-situ leaching mother liquor recovery of rare earth ores

Abstract

The invention provides a structure of a channel for recovering in-situ leaching mother solution of rare earth ore. The structure is that a brick wall is built at the liquid recovering channel; gaps for water seepage are reserved in one surface of the brick wall, close to the mountain, and the other surface of the brick wall, back on to the mountain, is avoided water seepage; the bottom part of the channel is subjected to anti-seepage treatment; the middle lower layer of the channel is filled whit gravel layers or sand layers; the upper layer of the channel is filled with small bamboo poles; PVC water pipes are buried in the bottom part of the channel, and pores are formed in the PVC water pipes. Rare earth mother solutions seeping from the mountain can be effectively covered through a channel body of the liquid recovering channel, and that the recovery rate of the mother solutions is reduced due to the seepage of the mother solution in collecting can be prevented through a blocking wall at one side of the channel body. The optimized solution recovering work can reduce the potential risks of the side slope such as cutting of the slope toe due to the flushing of the running mother solution to the slope toe of the mountain and can also reach the purpose of fixing and stabilizing the slope to a certain extent, and thus the probability of landslide of the slope toe of the mountain can be greatly reduced.

Description

technical field [0001] The invention belongs to the field of in-situ leaching ore collection of rare earth ores, and relates to a recovery channel structure for in-situ leaching mother liquor of rare earth ores. Background technique [0002] Ion-type rare earth ore is a unique rare earth resource in southern my country and rare in the world. The medium and heavy rare earth elements it contains have a very important impact on the development of new materials and new energy technologies in the world. [0003] The traditional mining methods are mainly barrel leaching, pool leaching, in-situ leaching and other methods to achieve. The operation process of the sodium chloride barrel leaching process is as follows: the ore mined after stripping the topsoil is transported to the room, and after screening, it is placed in a wooden barrel, and the sodium chloride solution is used as the leaching agent to leach the rare earth, and the obtained leachate is precipitated with oxalic acid ...

AI Technical Summary

Problems solved by technology

In the existing ionic rare earth mines, ditches are mostly used to drain the water directly into the liquid collection tank. This design often causes the place where the mother liquid seeps out to be easily collapsed, causing the clay layer on the surface of the mountain to slip and possibly damage the facilities. , causing more serious casualties and other accidents
