Skill is the air slaking ore bed being injected into ore leachate by the fluid injection well of grid arrangement under natural mode of occurence, in static pressure macerate condition
Under, ore leachate penetrates into seepage field, and, from unsaturation → saturation transition, seepage field is from unstable → steady statue mistake for Ore
Cross, thus produce steady flow.In here leaching ore deposit process of osmosis, ammonium ion and the rare earth ion in ore bed of ore leachate are handed over
The effect of changing, rare earth ion is added in solution, forms the mother solution with rare earth, and the mother solution of leaching is along ore body bottom basement rock water barrier
Surface current is pooled to collecting tank to massif outside intercepting gutter, or receives liquid level convergence to negative pressure（I.e. to ore bed bottom tunnel or lead
Fluid apertures is converged）, and along secondary negative pressure liquid collection system, being finally pooled to collecting tank, then be transported to hydrometallurgy workshop is carried out at rear technique

Problem.Its reason is probably：First, mining geology orographic condition is complex, and it is excessively simple that pattern is adopted in the leaching of employing, causes mother
Liquid is to deep seepage；2nd, ore body is in incomplete form, and ridge and foot of the hill elevation difference are larger, and ore bed Relative distribution is in massif
Top, massif bottom is longer without mine belt with underfall, and during leaching ore deposit, mother solution is flowed through without ore deposit area, back suction phenomenon occurs；
3rd, orebody thickness is little, and grade is relatively low, and infiltration coefficient is changed greatly, and seepage velocity is fast, and macerate vertebral body is little, and leaching mining area has larger blind
Area, leachate Rare-Earth Content is few；4th, liquid collection system arrangement is unreasonable, current in_situ leaching original mountain receive liquid mainly by tunnel,
Delivery hole derives the rare earth mother solution in massif, and mother solution is derived and blind area occurs, reclaims the rare earth mother solution less than the part.
For more effective, the safer rare earth resources for reclaiming ore body, the technology content except fully realizing in-situ leaching process carries out
Geological prospecting is supplemented, the geology landform of affiliated ore deposit section is found out, necessary underlying parameter, reasonable selection fluid injection is grasped, is received liquid scheme
And outside technological parameter, the blind area that also reply liquid collection system is likely to occur gives sufficiently understanding and analysis, and takes appropriate arranging
Bestow to solve.

Access adit liquid collecting hole is the herringbone liquid collecting tunnel of general direction.Delivery hole drain is to beat the m drains of φ 0.10 in ore body bottom
Hole, derives massif earth solution.Intercepting gutter be arranged vertically on liquid collecting pod apertures and tunnel lower section, for collect liquid collecting pod apertures and
The mother solution that tunnel is flowed out.According to chevron mountain looks geological conditions reasonable Arrangement liquid collection system, but still occur receiving liquid blind area, and engineering
Input is larger, does not reach rationally effectively recovering effect.
