Abstract: A method for producing a lithium compound, by which a high purity lithium compound can be produced from low-grade lithium carbonate containing impurities, such as salt water. The method includes: mixing lithium carbonate, an acid containing an organic acid, and water in a reaction tank 1 to produce an aqueous organic acid lithium solution containing an organic acid lithium; mixing the organic acid lithium and a metal hydroxide in a reaction tank 2 to produce an aqueous lithium hydroxide solution; and returning an organic acid, which is regenerated by using an electrochemical device from an organic acid metal by-produced by producing the aqueous lithium hydroxide solution to the reaction tank 1 and using the regenerated organic acid as the organic acid. An apparatus for producing a lithium compound, including the reaction tank 1, the reaction tank 2, the electrochemical device, and a return pipe, which each have a specific function.
