| titleOfInvention | A method for treating fluorine and chlorine-containing waste gas by utilizing scheelite slag |
| abstract | The invention discloses a method for treating fluorine and chlorine-containing waste gas by utilizing scheelite slag. The method includes: step 1, adding hydrochloric acid to a three-phase reactor containing the scheelite slag; step 2, feeding The fluorine-containing and chlorine-containing waste gas, the obtained fluorine-removed liquid recovers the valuable metals therein, and the obtained slag is used as the raw material for making glass. The advantages of the present invention lie in "using waste to treat waste", using scheelite slag to treat fluorine-chlorine waste gas, low cost, simple operation, and reducing the stockpiling of scheelite slag. Using this treatment method, the removal rate of fluorine and chlorine can reach more than 95%, the glass produced by using the obtained slag has good performance, and the obtained liquid after removing fluorine and chlorine can further recover valuable metals such as tungsten, tantalum and niobium. |
