The present invention relates to a method for separating gallium contained in an aqueous solution containing aluminum chloride as a main component. The solution containing aluminum chloride as a main component in the present invention refers to an aqueous solution made from aluminum ore such as bauxite, an aluminum compound such as alumina, or aluminum metal scrap, etc., by treating it with chlorine or hydrochloric acid. It is something. Such solutions usually contain gallium as an impurity, but depending on the raw material used, the concentration may not be negligible, and collecting it in such cases is a problem in terms of resource development. It is also desirable from the viewpoint of improving the purity of aluminum chloride. Methods for separating gallium from an aqueous solution containing aluminum chloride as a main component include a method of solvent extraction of gallium using ether or ketones, or a method of adsorbing gallium to an anion exchange resin. However, in the former, iron present as an impurity is extracted with the same efficiency as gallium, which is an obstacle when collecting gallium from the extracted part, and in the latter, iron is extracted with the same efficiency as gallium. Because the operation was performed at a low aluminum chloride concentration, a large amount of hydrogen chloride gas was required to separate aluminum chloride from the mother liquor after gallium separation. As a result of conducting research to resolve the deficiencies of the known techniques described above, the present inventor has discovered that nonionic MR type resin preferentially adsorbs gallium from a highly concentrated aqueous solution of aluminum chloride. The present invention was made based on this discovery. That is, the present invention is characterized in that an aqueous solution containing aluminum chloride as a main component is brought into contact with a nonionic MR type resin, and coexisting gallium is preferentially adsorbed onto the resin. This invention relates to a method for separating gallium. The nonionic MR type resin used in the present invention is, for example, the product name Biobeads SM-2, SM
-4, SM-7, Diamondion HP-20, Amberlight XAD-2, XAD-4, XAD-7,
Examples include XAD-8. Furthermore, an effective concentration of aluminum chloride in the solution is 2 mol/or more, and free hydrochloric acid in the solution does not pose a problem. In this way, the present invention can be operated with a highly concentrated aluminum chloride solution, which facilitates the precipitation of aluminum chloride from the mother liquor after gallium separation, and furthermore, it is possible to reduce the entrainment of iron into the separated gallium, so it is extremely useful. It has a high value. Next, the present invention will be explained with reference to Examples. Example 1 Dried Bio-beads SM-7 were soaked in methanol in advance, and then washed with a large amount of distilled water to remove methanol, transferred onto a glass filter, and distilled water adhering to the resin surface was removed by suction. Then seal tightly and store. 330mg of this resin
(equivalent to 100 mg dry weight) of the composition shown in Table 1.
In addition to 2.80 mol/101 ml of aluminum chloride solution,
Shake for 6 hours to adsorb gallium. After shaking, strain the resin using a glass filter,
Elute gallium by washing with 50 ml of mol/nitric acid.
The composition of the eluate is shown in Table 1. 82.8% of gallium in the stock solution was separated, 33.5% of iron and aluminum
This was followed by 0.6%.

After shaking, strain the resin through a glass filter and wash with 0.1 mol/100 ml of nitric acid to elute gallium. The composition of the eluate is shown in Table 2. 91.7% of gallium in the stock solution was separated,
This was accompanied by 21.3% of iron and 0.6% of aluminum.
