Biological decomposition of monazite by using phosphate solubilizing bacteria

摘要

The present invention relates to a technique for biologically decomposing monazite using a phosphate-dissolving microorganism to recover a rare earth metal. (B) adding monazite to the culture medium; (c) feeding microorganisms into the medium of step (b); and (d) ) Culturing the microorganism in step (c); and (e) leaching the rare earth metal from monazite using the cultured microorganism in step (d). . / RTI According to the present invention, rare earth metals can be economically recovered, and the process is simplified compared to conventional processes, while environmental pollution is not caused.
