Embodiment 1

[0079] Embodiment 1 The original diversion hole directly collects liquid

[0080] The specific operation process is as follows:

[0081] a. Use a thousand-meter drill to extend and drill diversion holes 1 to the inside of the mountain on the side wall of the mountain, with a diameter of 10cm, a hole depth of 45m, and a spacing of 0.25m;

[0082] B, inject ammonium sulfate solution from liquid injection well 8;

[0083] C, the ammonium sulfate solution flows through the mountain body 7, and the ammonium ion and the rare earth ion in the mountain body exchange and react to generate a rare earth sulfate solution (i.e. mother liquor), and the mother liquor flows out from the roadway and the diversion hole 1 to the liquid collection tank through seepage;

[0084] After the seepage is stabilized, the blind hole rate of the diversion hole in the tea garden plate is about 30%, and the liquid collection volume of about 15% is 2-3m 3 / hole d, about 50% of the liquid collection volume...

Embodiment 2

[0085] Embodiment 2 adopts bridge type filter tube to receive liquid

[0086] The specific operation process is as follows:

[0087] a. Use a thousand-meter drill to extend and drill diversion holes 1 to the inside of the mountain on the side wall of the mountain, with a diameter of 10cm, a hole depth of 45m, and a spacing of 0.25m;

[0088] b. Immediately after the diversion hole 1 is formed, connect and insert the bridge filter tube 2 in sections with a jack;

[0089] C, inject ammonium sulfate solution from liquid injection well 8;

[0090] D, the ammonium sulfate solution flows through the mountain body 7, and the ammonium root ion and the rare earth ion in the mountain body exchange reaction to generate a rare earth sulfate solution (i.e. mother liquor), and the mother liquor flows out from the roadway and the bridge filter pipe 2 through seepage and collects in the liquid receiving tank;

[0091] After the seepage is stable, according to the statistics, the blind hole ...

Embodiment 3

[0092] Embodiment 3 adopts the inventive method to collect mother liquor

[0093] The specific operation process is as follows:

[0094] a. Use a thousand-meter drill to extend and drill diversion holes 1 to the inside of the mountain on the side wall of the mountain, with a diameter of 10cm, a hole depth of 45m, and a spacing of 0.25m;

[0095] b. Immediately after the diversion hole 1 is formed, connect and insert the bridge filter tube 2 in sections with a jack;

[0096] c. At the orifice of the diversion hole 1, block the gap between the bridge filter tube 2 and the diversion hole 1; the outlet of the bridge filter tube 2 is connected to the tee fitting 3; the other two pipes of the tee fitting 3 The mouth is respectively connected to the water outlet pipe 4 and the intake valve 5; the water outlet of the water outlet pipe 4 is connected to the water outlet valve 6;

[0097] D, inject ammonium sulfate solution from liquid injection well 8;

[0098] e, the ammonium sulfa...

Abstract

The invention discloses a method for improving the collection efficiency of ionic rare earth in-situ leaching mother liquor, and belongs to the technical field of in-situ leaching and mining. In the present invention, after the diversion hole (1) is formed, the bridge filter tube (2) is inserted immediately; at the orifice of the diversion hole (1), the bridge filter tube (2) and the diversion hole (1) are blocked. the gap between; the outlet of the bridge filter tube (2) is connected to the three-way pipe fitting (3); the other two nozzles of the three-way pipe fitting (3) are respectively connected to the water outlet pipe (4) and the inlet valve (5); The water outlet of the water pipe (4) is connected with the water outlet valve (6); when the mother liquid in the water outlet pipe (4) is full, close the inlet valve (5), open the water outlet valve (6), and collect the mother liquid. The present invention installs the bridge-type filter tube (2) on the original seepage effect, and adds the siphon effect, which increases the seepage velocity of the mother liquor in the mountain body, reduces the blind hole ratio and increases the seepage velocity, and the double effect improves the collection efficiency of the mother liquor .

Description

technical field [0001] The invention belongs to the technical field of ionic rare earth in-situ leaching and mining, and in particular relates to a method for improving the collection efficiency of ionic rare earth in-situ leaching mother liquor. Background technique [0002] Rare earth is a general term for 17 rare elements such as lanthanum, cerium and praseodymium. It is a group of new functional materials with multiple properties such as electricity, magnetism, light and biology. An important basic material for national defense construction. Rare earths are widely used, and there are many kinds of functional materials that require the use of rare earths. A large-scale high-tech industrial group is being formed, with very broad market prospects and extremely important strategic significance. The ionic rare earth resources in the five southern provinces including Jiangxi and Guangdong are medium-heavy rare earth resources. So far, they have only been discovered in my coun...
