A method for producing a lithium-containing solution is provided in which a solution resulting from an elution step is made to have an increased lithium content and the amount of the solution in a step succeeding the elution step is reduced, thereby reducing the cost of lithium production. The method for producing a lithium-containing solution includes, in the following order, an adsorption step, an elution step in which lithium manganate resulting from the adsorption is brought into contact with an acid-containing solution to obtain an eluate, and a manganese oxidation step. The elution step comprises a first elution step, in which the acid-containing solution has a high H+concentration, and a second elution step, in which the acid-containing solution has a lower H+ concentration than in the first elution step. The second elution step is performed after the first elution step. Due to the configuration, elution is efficiently performed in the first elution step and, in the second elution step, there is no need of heightening the hydrogen ion concentration of the acid-containing solution and the amount of an acid to be added to the acid-containing solution can hence be reduced. Thus, the amount of the eluate to be used in the manganese oxidation step can be reduced.

The present invention provides an electric furnace including: a furnace body; and a plurality of electrodes that are provided so as to hang down into the interior of the furnace body from a top section thereof. The raw material is heated and melted in the furnace body by energizing the electrodes and a molten material consisting of a slag and a metal is generated. The electric furnace is configured so that the overall heat transfer coefficient of a side wall of the furnace body is lower than the overall heat transfer coefficient of a side wall of the furnace body, the side wall coming into contact with a layer of the metal formed in a bottom layer, the side wall coming into contact with a layer of the slag formed in a top layer, and said layers being formed in the molten material due to gravity separation.
The present invention provides a method for producing a valuable metal from a starting material that contains waste lithium ion batteries, the method being capable of effectively obtaining a metal which has a reduced phosphorus content. The present invention provides a method for producing a valuable metal from a starting material that contains waste lithium ion batteries containing phosphorus, the method comprising: a melting step in which the starting material is melted, thereby obtaining a melt; and a slag separation step in which slag is separated from the melt and an alloy containing a valuable metal is recovered. According to the present invention, an alloy is recovered, while making it sure that the recovery ratio of cobalt from the starting material is from 95.0% to 99.6%, thereby suppressing the phosphorus content in the alloy to 0.1% by mass or less.
