| titleOfInvention | Titanium component recovery method and titanium oxide manufacturing method |
| abstract | PROBLEM TO BE SOLVED: To recover a titanium component or calcium in titanium oxide obtained by using calcium hydroxide as a neutralizing agent in a method for recovering a titanium component from a effluent containing a titanium compound or a method for producing titanium oxide. To provide a method for recovering a titanium component having a low content or a method for producing titanium oxide. A method for recovering a titanium component from a effluent containing a titanium compound, wherein the effluent containing the titanium compound is brought into contact with water to hydrolyze the titanium compound (1), and a hydrolysis treatment. A primary neutralization treatment was performed in which calcium hydroxide or calcium oxide was added as a neutralizing agent so that the pH of the treated liquid was 1.5 or more and less than 2.5, and then the primary neutralization was performed. A step of subjecting the treated liquid to a secondary neutralization treatment in which calcium hydroxide or calcium oxide is added as a neutralizing agent so that the pH becomes 2.5 or more and 5.9 or less to obtain titanium hydroxide (a step of obtaining titanium hydroxide. 2) A method for recovering a titanium component, which comprises: [Selection diagram] Fig. 1 |
