  • Publication number: 20250092783
    Abstract: The present disclosure provides a method and system for mining rare earth ore using a direct current. The system includes: liquid injection holes arranged in a mining area; electrodes arranged in the liquid injection holes; a leaching agent added into the liquid injection holes; and an electrification control system dividing the mining area into M equal parts and electrifying the electrodes using a cyclical alternate electrification method from 1 to M. In an Nu electrification cycle, all electrodes of an (M×n+N)th row are connected to a positive electrode of a power supply, and all electrodes of an (M×n+N+1)th row are connected to a negative electrode of the power supply. The cyclical alternate electrification method reduces at least (M?1)/M of power consumption, and the rare earth mining efficiency is improved.
