In-situ leaching of molybdenum and uranium by percarbonate and chloride-hypochlorite solutions

Записки Горного института, 2022
In-situ leaching of molybdenum and uranium is becoming an increasingly common process. The features of the material composition of ores, leading to a decrease in their filtration properties, were considered.

Mesoscopic Process Simulation of In Situ Leaching of Ionic Rare Earth Based on NMRI Technology

Adsorption Science & Technology, 2023
In order to simulate and calculate the leaching process of ionic rare earths more realistically, a digital model of ionic rare earths with real size, shape, seepage channel, and pore ratio and distribution at the mesoscopic scale was constructed based on

Investigation of the Impact of Leaching Agent Concentration and pH on the Stability of Agglomeration of Ion-Absorbed Rare Earth Deposits

Geofluids, 2023
Ion-absorbed rare earth deposits react with the leaching agent during the in situ leaching process through ion exchange and hydration, which change the stability of ore agglomerates and even result in mining slopes or landslides.

Analysis of Slope Stability in Ion-Adsorption Rare Earth Mine Under In Situ Leaching Condition

Applied Sciences
Ionic rare earth ores are primarily extracted through in situ shallow well leaching. The leaching solutions engage in a physical–chemical coupling effect with the rare earth ores, which diminishes the strength parameters of weathered ore layers.

Recovery of uranium from low concentration leach liquor of acid in-situ leaching

IOP Conference Series: Materials Science and Engineering, 2017
For problems of environment protection and cost in uranium recycle, the process flows of ion exchange and Eluex, which recovered uranium from low concentration leach liquor of acid in-situ leaching, were studied. Although the flow sheet of ion exchange process was simple, the Eluex process had an advantage over it due to large quantity of effluent and ...

Hydrodynamics control for the well field of in-situ leaching of uranium

Nuclear Engineering and Technology
In this study, the groundwater hydrodynamics of two adjacent well sites were simulated under different pumping-injection ratios. The aim is to select an optimal pumping-injection ratio that can ensure the groundwater of the two well sites don't affect ...
