The present invention relates to a method of electrolytic reduction of a rare earth metal through a method of setting an electrolytic reduction condition when a metal is electrolytically reduced from a raw material containing a metal component using an electrolytic bath containing a cathode, an anode, and a supporting electrolyte. The present invention provides a method of predetermining a contact area and an amount of electrolytic support salt to obtain a target current density, and a method of predetermining an additional feed rate of the raw material. Accordingly, the present invention is able to provide an optimal electrolytic temperature and current density range during electrolytic reduction of the metal, and improve an efficiency of current.(S10) Set components and composition ratio of electrolytic support salt(S20) Set an electrolytic temperature(S30) Set applied current or voltage, and set current density of a cathode and an anode(S40) Contact area between the cathode and the electrolytic support salt, and the anode and the electrolytic support salt(S50) Electrolytic bath shape, size, a shape of the cathode and the anode, size and distance between the cathode and the anode(S60) Derivation of input amount of electrolytic support salt and initial amount of a raw material(S70) Derivation of additional feed rate of the raw materialCOPYRIGHT KIPO 2017
