简介 One embodiment of the present invention relates to a method for extracting rare metal elements, comprising : a first step of manufacturing an extraction remainder by reacting an extraction solvent including halogen acid and fly ashes; and a second step of adding a non-halogen acid extraction solvent to the extraction remainder, and reacting the extraction remainder by applying an ultrasonic vibration heat source. Thus, the present invention is able to highly efficiently extract yttrium (Y), neodymium (Nd), and gallium (Ga) from fly ashes which are wastes generated from electric power generation.COPYRIGHT KIPO 2018
