For the industrial internet support module 12, a basic platform, an internet of things, edge calculation, a data center and the like can be included, based on private cloud, network, edge and end architecture can be adopted, and industrial mechanism models such as digital twin mines, digital twin factory models and the like, data models, experience models, fusion models and the like are integrated, all production sensing terminals and corresponding production management and control modules are connected, and data acquired by all production sensing terminals are transmitted to the corresponding production management and control modules, so that the mining full-information three-dimensional visualization, mining leaching digital twin, mine safety monitoring, hydrometallurgy workshop monitoring, environment monitoring, data analysis, production households, energy households, environmental protection households, safety households, equipment households and other regional procedures and whole plant-level production management and control business application are realized.
Aiming at the production control module 13, including but not limited to an in-situ mineral leaching process production control module, a mineral resource production control module, a rare earth mother liquor hydrometallurgy process production control module, a characteristic pollutant emission concentration monitoring production control module, a production data display module and the like, data are acquired from a production perception terminal through an industrial internet support module, and the production process is controlled.
In a specific application scene, the industrial internet support module is embedded with an in-situ leaching coupling model, the production control module comprises an in-situ leaching process production control module, the in-situ leaching process production control module is used for carrying out in-situ leaching process production control according to the in-situ leaching coupling model, leaching data are acquired from production sensing terminals arranged in an in-situ leaching mining area through the industrial internet support module, and the mine in-situ leaching process is controlled based on the in-situ leaching coupling model according to the leaching data. The in-situ leaching coupling model is specifically used for constructing an in-situ leaching coupling model of the target ionic rare earth ore according to leaching data based on a porous medium structure, solving the in-situ leaching coupling model to obtain a simulated leaching process, and controlling the mine in-situ leaching process based on the simulated leaching process.
In the embodiment of the application, an in-situ leaching coupling model is firstly constructed, and it is required to be noted that the mineralization process of the ionic rare earth ore is accompanied by strong weathering, and most ore-containing areas are distributed in the fully weathered layer, so that the ore body can be regarded as a porous medium. The ore body of this type is mainly composed of coarser framework particles and finer loose particles, the framework particles being immobile, forming the framework of the ore body. Loose particles are present in the pores of the ore body and can move within a certain range. The porous media structure may also be referred to as a multiphase system consisting of a solid framework and a pore fluid, since pores exist between the solid framework and form pore channels within which gas and/or liquid phases typically exist and can circulate. Because the pore channel is narrow, the specific surface area of the solid particles is large, so that the solid particles have strong adsorption capacity, and besides rare earth ions, water molecules in the environment can be adsorbed on the surface to form immobilized water. Based on the above, in-situ leaching coupling model of the target mine based on the porous medium structure can simulate the leaching process of the rare earth ion ore more accurately. In particular, the flow of fluid within the pore channels of the porous medium is known as percolation. When in-situ leaching, the leaching agent enters the ore body through the liquid injection well, flows along the pore channels in all directions, solute ions (ammonium ions) dissolved in the leaching agent migrate to the surfaces of solid mineral particles under the actions of convection and self concentration gradients, then undergo ion exchange reaction with rare earth ions adsorbed on the surfaces, and the replaced rare earth ions enter liquid flow under the same migration conditions, so that the leaching purpose is realized. Based on this, the ion rare earth ore leaching process includes both a seepage process of a leaching agent in a porous medium ore body, a solute transport process, and a physical-chemical process of an ion exchange reaction, wherein the essence of the chemical reaction is a heterogeneous reversible ion exchange process between a solid phase and a liquid phase. In the embodiment of the application, through research and arrangement field engineering data, when the mineral leaching agent is continuously infiltrated through the liquid injection hole, the fully weathered layer (the mineral bearing layer) is continuously infiltrated and saturated, and the mineral bearing layer is basically in a saturated state in the later period of liquid injection. In addition, by analyzing the leaching mother liquor collection data of the mined mining area, the liquid injection amount and the recovery amount can be found to be basically equal after the actual liquid injection period, which indicates that the mining body basically reaches the saturated state. Based on the collected relevant geological data, the ore-bearing layer can be considered to be distributed above the underground water level in the ore body, the lower limit of the bottom plate of the ore body is higher than the underground water level, the condition that the leaching liquid flows into the underground water system in a large scale is not shown, the boundary condition of the submerged surface can be ignored, and the liquid collecting mode is only required to be considered as the boundary condition of the flow. Based on this, a seepage process mechanism submodel can be constructed based on saturated seepage characteristics, as shown below,
wherein K is xx Represents the permeability coefficient in the x-direction, K yy Represents the permeability coefficient in the y-direction, K zz The permeability coefficient in the z direction is represented, h represents the water head height, W represents the source and sink terms, S s Indicating the unit water storage coefficient.
The transport process of solutes in pore channels of ore bodies is attributed to physical processes, and the solutes migrate both with the movement of the leaching agent solution and diffuse under the effect of their own concentration gradient and are in a continuously varying state, so that the main mechanisms affecting the transport of solutes are convection and diffusion. In the embodiment of the application, a convection process mathematical expression equation and a hydrodynamic dispersion process mathematical expression equation are respectively established according to the principle of mass conservation, and are combined to obtain a convection-dispersion equation describing solute transport, as shown in the following,
wherein θ represents the volume water content, C aq Represents the concentration of solute, D represents the hydrodynamic diffusion coefficient,indicating the rate of seepage. In the case of saturated seepage, the water content was a constant value. Therefore, the solute transport process mechanism submodel, as shown below,
ion exchange processThe mass is the ion exchange reaction that occurs between the solute cations and the rare earth ions adsorbed in the fully weathered layer. The specific chemical reaction formula is ammonia sulfate(or magnesium nitrate->) The ion exchange process can be regarded as an equivalent charge exchange, i.e. 3 ammonium ions exchange 1 rare earth ion, for which an adsorption process is performed; for rare earth ions, a desorption process is used.
Based on this, the establishment of the ion exchange reaction process mechanism submodel is mainly based on the thermodynamic equilibrium constant when the reaction reaches instantaneous equilibriumWherein K represents thermodynamic equilibrium constant, and a represents activity of each substance after participating in ion exchange reaction. Further, the mass concentration can be expressed as
And finally, sequentially coupling the seepage process mechanism submodel, the solute transport process mechanism submodel and the ion exchange reaction process mechanism submodel to obtain an in-situ leaching coupling model.
Further, since the percolation process, the solute transport process and the ion exchange reaction are closely related, the percolation process of the mineral leaching agent affects the transport process of solute cations of the mineral leaching agent and the concentration of the solute cations, and the solute cation transport process and the concentration of the solute cations of the mineral leaching agent affect the ion exchange reaction. Based on the method, the simulation of the ion rare earth ore leaching process can be realized by carrying out coupling solution through the simultaneous seepage process mechanism submodel, the solute transport process mechanism submodel and the ion exchange reaction process mechanism submodel. Because the seepage process mechanism submodel and the solute transport process mechanism submodel are both second-order nonlinear partial differential equations, the two nonlinear partial differential equations are difficult to directly solve, and therefore, in the embodiment of the application, a finite element method is adopted, and the initial condition and the boundary condition are combined to solve. Specifically, the solving process can be converted into an energy integration extremum problem, namely a functional extremum problem, according to the variational principle, the partial differential equation, and corresponding initial conditions and boundary conditions, and a solution with the minimum energy is found from all solutions meeting the partial differential equation, the initial conditions and the boundary conditions. The finite element solving algorithm firstly disperses a solving domain into a finite number of tiny units to form basic units, and the units are connected through nodes. Further, an approximation function is assumed by constructing a piecewise interpolation function, algebraic equations are established on the respective units, and are assembled as a whole based on data transfer between nodes, forming an algebraic equation set, which may be expressed in the form of [ K ] { X } = { f }, where [ K ] represents a coefficient matrix, { f } represents a free Xiang Lie vector, and { X } represents the physical quantity to be solved. The partial differential equation solving is converted into algebraic equation solving based on the finite element solving algorithm, and the method is easy for computer program solving.
The characteristics (main influencing factors) and quantitative relativity of the characteristics influencing the mother liquor flow, the mother liquor concentration, the underground water level, the ammonia nitrogen concentration and the like can be found out by carrying out sensitivity analysis on the injection liquor flow, the permeability of the ore deposit and surrounding rock soil layers and the ion exchange balance coefficient, and the characteristic selection can be carried out. And adjusting model parameters according to the mother liquor flow and the thick and environment-friendly monitoring well water level and ammonia nitrogen content and side slope underground water level monitoring data collected by the liquid collecting roadway to carry out model correction so as to improve the accuracy of model simulation.
And finally, controlling the mine in-situ leaching process based on the simulated leaching process.
The production management and control module in the in-situ leaching process optimizes the leaching agent injection system, reduces the injection blind area by changing the injection range and the injection flow of the injection system, improves the recovery rate of rare earth resources, avoids excessive injection, and reduces the injection cost and the environmental pollution risk. In addition, the production management and control module in the in-situ leaching process optimizes a rare earth mother liquor collecting system, so that the collection of rare earth mother liquor is more facilitated by optimizing the arrangement of a liquid collecting system, the collection amount of the mother liquor is improved, meanwhile, the collection roadway of redundant mother liquor is reduced, and the engineering amount and investment are reduced.
