Abstract

See full text

Disclosed are a method for mining rare earth ore by electrification and a leaching agent for mining rare earth ore by electrification. The method includes: arranging 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; and adding a leaching agent into the liquid injection holes, and applying a direct current between electrodes by the electrification control system, the leaching agent including small molecular betaine. According to the present disclosure, the betaine can reduce the wetting resistance between solid and liquid phases, and promote the wetting and infiltration effects of a leaching agent solution on soil.
