| titleOfInvention | A kind of process of vanadium slag carbon alkali leaching hydrogen reduction method clean manufacturing barium oxide |
| abstract | The present invention relates to the processes that a kind of vanadium slag carbon alkali leaches hydrogen reduction method clean manufacturing barium oxide, and this method comprises the following steps：(1) fired to obtain calcining by vanadium slag and additive mixed ingredients；(2) after calcining obtained by step (1) being leached with carbon aqueous alkali, solid-liquor separation；(3) solution evaporation after detaching step (2) and detaches crystallisation by cooling, obtains sodium metavanadate crystal；(4) it will use hydrogen reducing, reduzate that barium oxide product is made through embathing dealkalize, atmosphere roasting, washing desalination, dry destruction step after sodium metavanadate crystal drying obtained by step (3).The present invention has the features such as vanadium recovery is high, and immersion liquid impurity content is few, and sodium metavanadate directly obtains barium oxide product, avoids the processing of ammonia nitrogen waste water, and technological process is simple, cleanliness without any pollution. |
