Flexible electrode tube for electrified rare earth mining and application method therefor

An application method for a flexible electrode tube for electrified rare earth mining, wherein each adopted flexible electrode tube comprises a flexible conductive plastic tube, a wire, and a joint zone, the flexible conductive plastic tube and the joint zone are integrally formed, and the joint zone has a plurality of annular grooves;

• the wire is embedded inside a tube wall of the flexible conductive plastic tube in a spiral manner, uniformly distributed from top to bottom, causing the wire to uniformly and efficiently transmit current throughout the entire tube wall, shortening a current transmission distance within the flexible conductive plastic tube, and reducing the overall resistance of the flexible electrode tube;
• the flexible conductive plastic tube features an open bottom configuration and a smooth outer wall, with the wire being a single metal wire;
• and the flexible conductive plastic tube has an outer diameter of 40-80 mm, a wall thickness of 2-4 mm, and a tube length of 3-21 m;
• and
• the application method comprises the steps of:
• S1, drilling liquid injection holes in a mining area, each with a diameter of 40-80 mm, and a bottom positioned 1-2 m above a bottom of a rare earth orebody;
• S2, slowly placing the flexible electrode tubes into the bottoms of the liquid injection holes, with top ends located at an interface between the rare earth orebody layer and a topsoil layer;
• S3, inserting fluid injection tubes into the liquid injection holes to lengths precisely reaching the joint zones of the flexible electrode tubes, the fluid injection tubes serving primarily to introduce leaching agents into the flexible electrode tubes;
• S4, fixing ropes connecting clamps to ground stand columns, inserting waterproof snap-fit joints of n cables into an n-to-1 waterproof connector, with 1<n<10, transferring this connector to a main cable and connecting it to the corresponding positive or negative terminal of a direct current (DC) power supply, and performing electrified rare earth mining;
• and
• S5, unplugging the cables of the flexible electrode tubes from the n-to-1 waterproof connector after mining completion, pulling out the fluid injection tubes, and extracting the flexible electrode tubes from the liquid injection holes by pulling the ropes for later use.
