1. A method for mining rare earth ore by electrification, comprising:
step 1: arranging at least two rows and at least one column of liquid injection holes in a mining area, arranging electrically conductive liquid injection pipes in the liquid injection holes, and connecting N electrically conductive liquid injection pipes in a same row in parallel to an electrification control system according to currents when each of the electrically conductive liquid injection pipes is electrified, wherein N≥2 and N is a positive integer; and
step 2: adding a leaching agent into the liquid injection holes, and then applying a direct current between the electrically conductive liquid injection pipes by the electrification control system,
wherein the leaching agent is selected from a leaching agent for mining rare earth ore by electrification;
wherein the leaching agent for mining rare earth ore by electrification comprises:
ammonium salt and small molecular betaine; or
calcium salt and small molecular betaine; or
magnesium salt and small molecular betaine; or
sodium salt and small molecular betaine; or
potassium salt and small molecular betaine.
