| titleOfInvention | The method that circulation hydrochloric acid microemulsion method produces pigment-level titanium dioxide |
| abstract | The invention discloses a kind of method that circulation hydrochloric acid microemulsion method produces pigment-level titanium dioxide, its main contents includes, using hydrochloric acid, acidolysis is carried out to Rich titanium blast furnace slag or ilmenite, acidolysis reaction obtains the organic microemulsion of acidolysis clear liquid to carry out extracting titanium, in the fine liquid pearl that titanium in acidolysis clear liquid is constituted by the microemulsion film in organic microemulsion is collected in, it is separated into organic extract liquid and raffinate, titanium back extraction is gone out by the organic extract liquid back washing agent obtaining, and the back extraction titanium liquid obtaining obtains Rutile type titanium dioxide through hydrolysis calcining.The impurity such as the ferrum in raffinate, aluminum, magnesium, vanadium, are extracted using organic microemulsion and remove, the regeneration hydrochloric acid obtaining can return to hydrolysis procedure.The method of the present invention, overcome the sulphuric acid circulating consumption height that the titanium white production method of prior art exists, it is difficult to industrialized problem, multiple side-products can be produced while producing titanium dioxide, make the resource in raw material obtain comprehensive reutilization, fundamentally solve the pollution problem to environment for the blast furnace slag. |
