Abstract
The present invention relates to in situ leaching technology suitable for ion type rare earth ore of a leaky bottom board, which adopts the following steps: ore body blasting looseness, ground groove liquid injection, drilling pressure liquid injection, drilling liquid collecting holes on the bottom of an ore body, arranging liquid collecting tubes in the liquid collecting holes, and connecting with a vacuum system. The present invention adopts a vacuum bottom closing and liquid collecting method, and realizes effective recovery of leaching liquid. The present invention has the obvious advantages of on mountain move and no environment pollution, and is suitable for developing and utilizing ion type rare earth ore.
Description
The invention belongs to ore body original place technical field of wet metallurgy.
Ion type rareearth ore now adopts leaching process production, promptly with manually taking ore and be transported to maceration in the mine-dipping pool, after having soaked, will soak slag again and take out of and be deposited in the tailings dam, and the defective of this technology is to cause loss waterborne, contaminate environment easily.
Existing in-situ leaching method coloured, precious metal is a shaft drilling method, and its practice is: hole in ore body, adopt blasting procedure with the ore body original place crushing; Inject ore leachate in the ore body surface sprinkling or to the ore body boring pressure; Ore leachate passes ore layer by gravity and pressure, and with ore generation chemical reaction, the ore leachate that contains metallic element constantly flows into the liquid collecting well that is lower than the ore body base plate, extracts ore leachate out ground with feed pump again.This technology is only applicable to the watertight ore body of base plate and country rock, and to the ore body (as ion type rareearth ore) of base plate leakage, as not blocking up the bottom reason, then can not compile on the ore body base plate because of leach liquor, can't reclaim and can not use.
Purpose of the present invention is exactly to soak the ore deposit problem for the original place that solves base plate meeting seepage ore body.The main practice is: by using negative pressure back cover vacuum drawing liquid way, realize the efficient recovery of leach liquor.
Technical scheme of the present invention is: 1, in the internal drilling of ion type rareearth ore ore body, carry out in-place blasting out; 2, inject ore leachate at ore body surface excavation groove infiltrating irrigation ore leachate or to the ore body boring pressure; 3, at ore body bottom Drilling level or inclination liquid collecting hole, 50～125 millimeters in aperture, 50～200 centimetres of spacings, the liquid collecting hole degree of depth is decided on the ore body situation, generally is no more than 15 meters; 4, in liquid collecting hole, install liquid collecting tube, 20～50 millimeters of liquid collecting tube internal diameters, length is determined according to the liquid collecting hole degree of depth, tube wall perforation, the outer wrap (cotton, fiber crops or nylon braid) that is tied with good permeability of pipe.After liquid collecting tube installs, with the tight shutoff in the space between liquid collecting hole aperture and the liquid collecting tube; 5, liquid collecting tube is connected with vacuum system.When vacuum pump is bled receipts liquid, form the vacuum seal bottom, leach liquor is drawn into air water separator, and discharges from the gate valve of bottom discontinuously, thereby reaches the recovery purpose.
Advantage of the present invention: the in-situ leaching that 1, is applicable to base plate meeting seepage ore body; 2, employing vacuumizes receipts liquid, can strengthen the content of useful metal element in ore leachate maceration speed and the increase ore leachate; 3, can shorten and soak the ore deposit cycle, improve output; 4, do not discharge tailings, nonpollution environment, the protection eubiosis.Be suitable for the development and use of the ion type rareearth ore of base plate meeting seepage.
Embodiment:
Adopt the present invention to carry out in-situ leaching test, test is carried out at the Jiangxi ion type rareearth ore.Elder generation is with half weathering ore body in-place blasting out during test, adopt ground groove infiltrating irrigation again and to ore body bore pressuring injection ore leachate, simultaneously in foot of the hill ore body pinching level to the parallel drawing liquid of ore body base plate Drilling hole, pumping pipe is installed in drawing liquid hole drill cutter back in the hole, be drilled with eyelet on the pipe, the pipe external parcel burlap, after pumping pipe is installed, the tube end of retaining outside the hole is connected with ground vacuum drainage system, the gap between the hole wall in the outer wall of aperture pumping pipe and drawing liquid hole is tightly stopped up with sand-cement slurry.At the trial, vacuum pump drawing liquid negative pressure is 13332～19998 handkerchiefs.Test-results: rare earth leaching yield 93.60%, to receive the liquid rate and reach 66.70%, rare earth is collected rate 68.88%, and every economy, technical indicator are better than the leaching process productive capacity.
Claims (4)
1, a kind of ore leaching process, comprise: the explosion and crushing ore body, inject ore leachate in ore body surface fluid injection or boring, operations such as material liquid pump pumping, it is characterized in that: at ion type rareearth ore bottom Drilling liquid collecting hole, install liquid collecting tube in the liquid collecting hole, tube wall is drilled with eyelet, the outer wrap that is tied with good permeability of pipe, pumping pipe is connected with ground vacuum system, air water separator.
2, technology according to claim 1 is characterized in: at ore body bottom Drilling level or inclination liquid collecting hole.
3, technology according to claim 1 is characterized in that: liquid collecting tube is made with plastics or metal.
4, technology according to claim 1 is characterized in that: the vacuum system that links to each other with liquid collecting tube, its vacuum tightness are 13332～19998 handkerchiefs.
