Description
Technical field
The present invention relates to a kind of recovery method of ion adsorption type rare earth ore, especially a kind of churning modular rare earth mining
Method.
Background technology
China is the most abundant country of rare earth resources in the world, have the title of " rare earth kingdom ", south based on heavy rare earth,
The north is based on light rare earth.Not only reserves are big for China rare earth mineral products, and wide in variety, quality is good, and deposit type is unique.
Ion adsorption type rare earth ore, also known as weathered superficial leaching rare-earth ore, it is with the presence of " ion phase " mineral shape, quilt
The rare-earth mineral being adsorbed on " carrier " mineral surfaces, the rare earth overwhelming majority in rare-earth mineral exists with cationic state, and
It is attracted on certain mineral carrier, such as absorption is in kaolinite, white mica aluminium silicate mineral or Fluoro-carbonate Minerals.Ion
Absorbent-type Rare Earth Mine is the ore body being made up of " ion adsorption type rare earth ore thing ", and southern RE ore to belong to ion type substantially dilute
Tu Kuang.
At present, the recovery method of ion adsorption type rare earth ore all adopts traditional In-situ leaching substantially, is not
Destruction ore body surface vegetation, do not peel off table soil, do not excavate with carry Ore in the case of, well pattern is directly arranged on ore body, it is sharp
With in electrolyte solution injection ore body of a series of shallow well (groove) by energy exchanged rare earth ion so as to hand over rare earth ion
Solution is acted on, and is then waited and is collected mother solution, and its stope liquid collection system is received liquid ditch and is collected using the foot of the hill substantially, and mother solution is in ore body
The spread condition in portion is difficult to control to.
Existing In-situ leaching, has the following disadvantages：
A, because of massif structure the reason for, the inhomogeneities of the infiltration coefficient of each several part in massif are same within the same time
Method fluid injection, solution penetrates into less where infiltration coefficient is little, and most solutions are oozed all along the big soil layer of massif infiltration coefficient
Thoroughly.In order to reach the waste water after the rare earth for leaching the little soil layer of infiltration coefficient must just inject substantial amounts of solution and process, so
Waste water after solution being caused where infiltration coefficient is big and being processed is superfluous.
B, within a certain period of time, the adsorbance of cation is directly proportional to the time, and the time is longer, and absorption cation is more, when
Seam thickness more than certain thickness, or soil layer infiltration coefficient very little when, penetrate into ore bed from liquid injection hole injection solution
The tunnel of bottom, needs long time, so causes the soil layer ion above tunnel to adsorb in a large number, and bottom ore deposit is leached completely
Layer, it is necessary to inject solution in a large number, so causing the consumption of water increases, and the consumption of water increase cause inflow tunnel in it is dilute
Native solution middle rare earth grade is just relatively low, so that production cost is larger.
C, the advantage due to solution diffusion are orientated, and the tank solution from liquid injection hole injection is less along the larger resistance in crack
Approach reaches from the hilltop the liquor collecting system at the foot of the hill, and it is logical that the leaching later stage is easily internally formed intrinsic big crack solution flowing in ore body
Road, leaching effect is substantially reduced, and this is also some Rare Earth Mines being terminated by leaching mother liquid concentration and judge that the Rare Earth Mine is exploited, but
Leach the reason for still obtaining the mother solution compared with GOOD TASTE, i.e. primary recovery again over time to terminate inside rear ore body
Fissured structure changes, and solution has been leached in diffusion process caused by the crack blind area in last time recovery process again.
Therefore, whether existing In-situ leaching leaches completely standard to ore body and is difficult to define, the difficulty to resource
Reclaimed with forming systematicness, production process is more extensive, relatively low to the response rate of resource, the low mother liquid concentration of formation was extracted
