Title:
PREPARATION METHOD FOR IONIC RARE EARTH LEACHING AGENT
Document Type and Number:
WIPO Patent Application WO/2024/008214
Kind Code:
A1
Abstract:
Disclosed in the present application is a preparation method for an ionic rare earth leaching agent. The preparation method comprises the following steps: (1) domesticating microorganisms by using a rare earth activated mineral powder culture medium to obtain a microbial suspension; (2) subjecting the microbial suspension and an additive to an amplification culture to obtain an amplification culture solution; and (3) uniformly mixing modified sesbania gum and the amplification culture solution to obtain an ionic rare earth leaching agent. The activated mineral powder in the present application is a mineral powder containing an active metal in nature that has a good cation exchange function after being activated, and the activated mineral powder and the ionic rare earth mineral powder are used as culture medium components to domesticate microorganisms, such that the microorganisms can survive in the ion solution, and the leaching rate of the collaborative leaching ionic rare earth is improved.
