AI Technical Summary
Existing technologies for extracting ionic rare earth ores, especially heavy rare earth ores, pose risks of environmental pollution and resource waste, and lack effective methods for selectively enriching microorganisms.
The Burkholderia contaminans GP4-1 microbial strain was used for bioleaching. The organic acids secreted by the strain, such as citric acid and oxalic acid, were used to desorb rare earth ions and selectively enrich heavy rare earth elements through complexation. The leaching was carried out in a green and environmentally friendly neutral environment.
It significantly improves the leaching rate and utilization rate of heavy rare earth elements, reduces the leaching of impurities, lowers the risk of environmental pollution, and realizes the efficient and selective extraction and economical utilization of rare earth resources.
