The utility model discloses a device for removing iron and magnesium from calcium carbonate. The device comprises a base, wherein a shell is arranged on the upper part of the base; a fixing pipe is arranged at the bottom of the inner side of the shell; a plurality of third through holes are formed in the lateral periphery of the fixing pipe; a bracket is arranged on one side of the base; a fixing plate is arranged on one side of the bracket; a second through hole is vertically formed in the fixing plate, and is located above the shell; a first motor is arranged on the upper part of the fixing plate; a speed changing box is arranged on the lower part of the fixing plate. The utility model provides a device capable of removing iron and magnesium carbonate impurities from calcium carbonate. The first motor of the device is capable of driving a stirring plate to stir a turbid liquid of calcium carbonate powder in the shell; hot water flows in the shell; the mixing efficiency of the hot water and calcium carbonate is improved, so that exposure of calcium carbonate and a strong magnet is improved; and the strong magnet can fully adsorb an iron component in the calcium carbonate conveniently.
