ion technology from fly ash by means of the industrial waste acid produced from titanium dioxide industry. It has been studied by tests that the various reaction factors influence the rate of aluminum abstraction. The best leaching conditions have also been determined. All of these results bring about a new aluminum abstraction method from fly ash using the industrial titanium-dioxide waste acid and a new way of the comprehensive reuse of the titanium dioxide waste acid and waste residue fly ash. It can be seen from this research results that this new technology of aluminum abstraction from fly ash using the industrial titanium-dioxide waste acid will significantly benefit the environment, economy and society.
