LEACHING METHOD OF RARE-EARTH METALS USING HYDROCHLORIC ACID FROM MANGANESE NODULE

摘要

The present invention relates to a leaching method of rare-earth metals from manganese nodule using hydrochloric acid solution and, more specifically, to a leaching method of rare-earth metals from manganese nodule using hydrochloric acid solution to leach rare-earth metals contained in the manganese nodule by stirring and heating the manganese nodule with the hydrochloric acid solution after mixing the same.
