Provided is a novel metal raw material manufacturing device capable of manufacturing magnesium hydroxide.　This metal raw material manufacturing device (4) includes a seawater supply unit (41), an electricity supply unit (42), an electrolysis unit (43), and a metal raw material collection unit (44). The seawater supply unit (41) includes a first seawater supply unit (411), the electricity supply unit (42) supplies electricity to the electrolysis unit (43), the electrolysis unit (43) includes a first reaction unit (431), the metal raw material collection unit (44) includes a first collection unit (441), and the first seawater supply unit (411) supplies first seawater to the first reaction unit (431). Sodium ions, chlorine ions, magnesium ions, and calcium ions are present in the first seawater. In the first reaction unit (431), hydrogen gas, chlorine gas, and hydroxide ions are produced in the first seawater through electrolysis of the first seawater using the supplied electricity, and the hydroxide ions react with the magnesium ions in the first seawater to produce magnesium hydroxide. The first collection unit (441) collects the produced magnesium hydroxide. |
