Example Embodiment
[0015] Example 1
[0016] S1. The by-product aluminum-containing red mud of chemical enterprises and metallurgical enterprises (the alumina content of aluminum-containing red mud is 10% by mass) is added with 20% by mass hydrochloric acid, and the mixed reaction is mixed to produce an unsaturated aluminum chloride solution , And then go through filtration, dehydration, and pressure filtration to remove impurities to make the solution clear and transparent;
[0017] S2. Add 1% by mass of aluminum particles to the solution for displacement reaction to replace metals with lower activity than aluminum in the solution, and then add 0.5% by mass of strong oxidant to reduce the iron in the solution, and then remove the organic by organic ion exchange resin Solvent; then remove iron through the macroporous adsorption resin ion exchange column, exchange other metal ions (copper, magnesium, arsenic, etc.) through different macroporous adsorption resins and cation adsorption resins, exchange ...

[0019] Example 2
[0020] S1. The by-product aluminum-containing red mud of chemical enterprises and metallurgical enterprises (the alumina content of aluminum-containing red mud is 15% by mass) is added with 25% hydrochloric acid, and the mixed reaction is made into an unsaturated aluminum chloride solution. Then go through filtration, dehydration, and pressure filtration to remove impurities to make the solution clear and transparent;
[0021] S2. Add 2% mass percentage of aluminum scraps to the solution to carry out a substitution reaction to replace metals with lower activity than aluminum in the solution, and then add 1% mass percentage of a strong oxidant to reduce the iron in the solution, and then remove the organic by organic ion exchange resin Solvent; then remove iron through the macroporous adsorption resin ion exchange column, exchange other metal ions (copper, magnesium, arsenic, etc.) through different macroporous adsorption resins and cation adsorption resins, excha...

[0023] Example 3
[0024] S1. The by-product aluminum-containing red mud of chemical enterprises and metallurgical enterprises (the alumina content of aluminum-containing red mud is 20% by mass) is added to 25% hydrochloric acid, and the mixed reaction is mixed to produce an unsaturated aluminum chloride solution. Then go through filtration, dehydration, and pressure filtration to remove impurities to make the solution clear and transparent;
[0025] S2. Add 5% by mass of aluminum powder to the solution for displacement reaction to replace the metal with activity lower than aluminum in the solution, then add 1% by mass of a strong oxidant to reduce the iron in the solution, and then remove the organic by organic ion exchange resin Solvent; then remove iron through the macroporous adsorption resin ion exchange column, exchange other metal ions (copper, magnesium, arsenic, etc.) through different macroporous adsorption resins and cation adsorption resins, exchange organics and inorga...
