Abstract:
In−situ leaching process of ion adsorption rare earth ore mother liquor flow direction has not been effectively monitored, the decrease of rare earth recovery rate and secondary
geological disasters caused by the unknown mother liquor flow have brought serious challenges to environmentally friendly and efficient mining. The in−situ leaching process of an ion−type rare earth ore block in Sanqiutian, Dingnan County, was continuously monitored by high−density electrical method to realize mother liquor flow direction monitoring. The results showed that the resistivity of mother liquor in the seepage area of the mine continuously decreased, while the resistivity of the bedrock and the seepage floor remained unchanged, and the direction of low resistance extension was the mother liquor flow direction. This method can effectively guide the layout of injection and collection system, improve the recovery rate of rare earth, realize the visualization of mother liquor recovery process, and help ion adsorption rare earth to develop in a green and efficient way.
