| titleOfInvention | A kind of alkaline process processes the method for iron red mud degree of depth dealkalize and ferrum enrichment |
| abstract | A kind of alkaline process processes the method for iron red mud degree of depth dealkalize and ferrum enrichment, the steps include: iron red mud and the strong base solution mixing that concentration is 300g/L～700g/L are carried out dissolution process, aqueous slkali and iron red mud volume mass proportioning are 4:1 20:1 (ml/g), leaching temperature is 200 300 DEG C, and the response time is 10 60min.After dissolution, solid-liquor separation obtains thick alkali liquor and dealkalize iron red mud, obtains rich scum after dealkalize red mud slag is scrubbed, in rich ferrum finishing slag sodium oxide content be not more than 1%, iron oxide content more than 40%, can be directly used for blast furnace ironmaking.The method leaching temperature and pressure are relatively low, and dealkalize effect is good, and process in leaching will not produce secondary pollution. |
