| titleOfInvention | A kind of method preparing rutile titanium dioxide |
| abstract | The invention belongs to inorganic metal compound preparation field, particularly, the present invention relates to a kind of method preparing rutile titanium dioxide.The method preparing rutile titanium dioxide of the present invention, comprises the following steps: 1) join in titanium slag by sulfuric acid, obtain acid hydrolysate; 2) acid hydrolysate dilute sulphuric acid step 1) obtained leaches; 3) by step 2) the titanium liquid that obtains filters, adds ammoniacal liquor, then add reductive agent, obtain TiO in gained filtraten 2 concentration is the titanium liquid of 100 ~ 130g/L; 4) titanium liquid step 3) obtained is hydrolyzed, and filters, and obtains hydrated titanium dioxide solid and the hydrolysising mother liquid of white; 5) hydrated titanium dioxide calcining step 4) obtained, obtains rutile titanium dioxide.The present invention proposes the clean preparation method being produced rutile titanium dioxide by low-grade titanium slag, for the comprehensive utilization of titanium resource and the preparation of titanium dioxide (titanium dioxide) provide an effective approach. |
