Due to this configuration, when the hydrous polymer has a predetermined moisture content, since the granular body is gelatinous, partial loss thereof no longer occurs and the durability of the granular body is improved. In addition, because the hydrous polymer allows a liquid such as seawater to pass, the entire lithium adsorbent can come into contact with this liquid and the ability of the lithium adsorbent can be efficiently utilized.

Abstract

Provided is a method for separating impurities and cobalt without using an electrolysis process from a cobalt chloride solution containing impurities and producing a high purity cobalt sulfate. The production method includes: a first solvent extraction step (S1) of bringing an organic solvent containing an alkyl phosphoric acid-based extractant into contact with a cobalt chloride solution containing impurities, and extracting zinc, manganese, and calcium into the organic solvent to separate to remove zinc, manganese, and calcium; a copper removal step (S2) of adding a sulfurizing agent to a cobalt chloride solution and generating a precipitate of sulfide of copper to separate to remove copper; a second solvent extraction step (S3) of bringing an organic solvent containing a carboxylic acid-based extractant into contact with a cobalt chloride solution and back extracting cobalt with sulfuric acid after extracting cobalt into the organic solvent to obtain cobalt sulfate solution; and a crystallization step (S4) of the cobalt sulfate solution obtained after having undergone through the second solvent extraction step (S3). These steps are sequentially executed. Without using an electrolysis process, a high purity cobalt sulfate is directly produced by separating cobalt and impurities containing manganese.

Abstract

The present invention provides a method for efficiently obtaining a solution that contains nickel and/or cobalt from lithium ion battery waste or the like, which is an alloy that contains nickel and/or cobalt and copper. The present invention is a treatment method for an alloy, the method being used for the purpose of obtaining a solution that contains nickel and/or cobalt from an alloy that contains nickel and/or cobalt and copper. This treatment method for an alloy comprises a leaching step in which the alloy is subjected to a leaching treatment by adding an acid solution to the alloy in the coexistence of a sulfurizing agent, thereby obtaining a leachate and a leaching residue; and in the leaching step, the leaching treatment is carried out while maintaining the copper concentration in the reaction solution within the range of 0.5 g/L to 15 g/L by adding a divalent copper ion source thereto. Moreover, in the leaching step, the leaching treatment is carried out while maintaining the redox potential of the reaction solution at 50 mV or more, using a silver/silver chloride electrode as a reference electrode.

Abstract

Provided is a method for producing a lithium-containing solution that allows increasing a content rate of lithium in a solution after an eluting step, and suppressing an amount of an eluted solution used in a process after the eluting step, thus suppressing production cost of lithium. Provided is a method for producing a lithium-containing solution that allows increasing a content rate of lithium in a solution after an eluting step, and suppressing an amount of an eluted solution used in a process after the eluting step, thus suppressing production cost of lithium. A method for producing a lithium-containing solution includes an adsorption step of bringing a lithium adsorbent obtained from lithium manganese oxide in contact with a low lithium-containing solution to obtain post-adsorption lithium manganese oxide, an eluting step of bringing the post-adsorption lithium manganese oxide in contact with an acid-containing solution to obtain an eluted solution, and a manganese oxidation step of oxidating manganese to obtain a lithium-containing solution with a suppressed manganese concentration. The adsorption step, the eluting step, and the manganese oxidation step are performed in this order, and the acid-containing solution includes the eluted solution with acid added. The method allows the usage amount of the acid in the eluting step to be suppressed, the content rate of lithium in the eluted solution after the eluting step to be increased, and thus the production cost of the lithium-containing solution to be suppressed.
