Description
Technical Field
The invention belongs to the technical field of monitoring of ion adsorption type rare earth ores, and particularly relates to a nondestructive monitoring method for in-situ leaching exploitation of ion adsorption type rare earth ores.
Background
The ion adsorption type rare earth ore is a novel exogenous rare earth mineral which is discovered in the Jiangxi of China in 1969, and the mineral is widely distributed in the Jiangxi, guangdong, guangxi, hunan, fujian, yunnan, zhejiang and other south provinces of China. The ionic rare earth is adsorbed on minerals in an ionic form, such as kaolin, montmorillonite, most of which is like soil, and the content of the ionic rare earth is about 0.3 to 0.05 percent, and the ionic rare earth can be leached out by electrolyte. The ion-adsorption rare earth ore has complete rare earth distribution and is rich in medium and heavy rare earth elements, thereby being a valuable strategic mineral resource in China.
The ion type rare earth is subjected to pond leaching, heap leaching and in-situ leaching in sequence, the in-situ leaching process is vigorously carried out at present, the ion type rare earth is considered to be the most environment-friendly mining mode at present, surface soil stripping and ore body excavation are not needed, liquid injection wells are distributed in an ore area according to certain well pattern parameters, leaching solution is injected into the ore body through wells (holes), ammonium ions in the leaching solution desorb the rare earth ions on the surface of clay through chemical replacement reaction, formed rare earth leaching solution permeates and flows in the ore body, liquid accumulation ditches or liquid collection roadways at the positions of mountain feet are converged, impurities are removed through a hydrometallurgy workshop, and finally ammonium bicarbonate is used for precipitation, so that the purpose of recovering the rare earth resources is achieved.
Through efforts of about 50 years, although the ionic rare earth extraction process represented by in-situ ore leaching is established, in the ionic rare earth development process, the randomness of resource leaching rate is high due to the fact that the distance of a liquid injection well pattern and the liquid injection speed are determined by experience, and the problems of rare earth leaching position, leaching liquid flowing position and the like are not well solved. An effective leaching liquid permeation theory and a migration monitoring mechanism are not established, and double losses of leaching solution and rare earth resources are easily caused.
The in-situ leaching process has the advantages that the tank leaching process and the heap leaching process are not comparable, but has more serious environmental risks. In-situ leaching requires injection of a large quantity of leaching solution (larger than the amount used in tank leaching and heap leaching, and raw oreAdding about 5 tons of ammonium sulfate into 1 ton of rare earth, injecting a large amount of mineral leaching solution into an ore body,
the ammonia nitrogen is adsorbed and stayed in the upper body, continuously migrates and transforms in soil body along with the leaching and infiltration action of rainfall and continuously migrates to surrounding soil and water body, and excessive ammonia nitrogen can cause a series of serious ecological environment problems such as soil pollution, withered surface vegetation, salinization of soil, eutrophication of water body and the like, and even threaten the health of human body. Research shows that after the mine is abandoned for many years, high-content ammonium nitrogen can still be detected in surrounding soil and water, and the rare earth ore residue is closed for 5 years
The highest content still can reach 119.2mg.kg -1 The ecological environment of the rare earth closed mining area is harmed for a long time by ammonia nitrogen pollution, and practical ammonia nitrogen compound migration distribution rule research and related treatment measures are urgently needed to be provided, and the migration change rule is waiting for long-time dynamic monitoring.
The patent CN113933354A discloses a liquid injection seepage monitoring method for in-situ leaching of ionic rare earth ore, which combines a high-density resistivity method with underground water drilling observation to realize detection of an underground seepage migration direction, a confluence area and an influence range of a liquid injection area. However, the patent limits the use of the high-density resistivity method, and because the deep detection part of the method is limited, the method has no construction possibility for mines with large topographic relief or large weathered layer thickness, is only suitable for monitoring the seepage of the leaching solution in the mining process, and cannot be used for monitoring the migration of pollutants after mine closure. And the patent is actually a description of an application example, and the corresponding theoretical basis is lacked, particularly the reason why the mineral leaching solution has no basis for the change of the resistivity of the rock soil.
Based on the ammonia nitrogen migration problem existing in the rare earth in-situ leaching, the method is based on a plurality of field test summaries. The invention provides an ion-adsorption-type nondestructive monitoring method for in-situ leaching exploitation of rare earth ores by combining technical means such as a geophysical resistivity method, geological drilling sampling, hydrogeological test and the like. The invention can effectively solve the problems of difficulty in tracking the leaching solution, delineating the leaching boundary and monitoring the pollutant environment after ore closing in the leaching process, provides basic data support for the in-situ leaching mining and liquid injection construction of the ionic rare earth, and has important significance for perfecting the migration process of the soil nitride in the ionic rare earth mining area and guiding the treatment of ammonia nitrogen pollution. Is beneficial to the construction of ecological green and sustainable mine.
