| titleOfInvention | The method of a kind of pelletizing vanadium slag roasting |
| abstract | The invention discloses the method for a kind of pelletizing vanadium slag roasting, said method comprising the steps of: a, sodium salt additive, binding agent are added to the water are mixed with viscous aqueous solution respectively; B, vanadium slag is broken and the vanadium slag after fragmentation and described viscous aqueous solution are mixed to get compound, described compound is pressed into pelletizing; C, described pelletizing is carried out high-temperature roasting obtain grog, the grog water logging after fragmentation is gone out by described chamotte crushing, obtains after filtration containing vanadium leachate.The present invention carries out the pelletizing vanadium slag roasting method of high-temperature roasting vanadium extraction again after adopting and sodium additive, binding agent and vanadium slag being made pelletizing, substantially increase the rate of recovery of vanadium, it also avoid the bonding phenomenon that vanadium slag produces in high-temperature calcination process simultaneously.Present invention process is simple and easy to use, wide accommodation, cost are low, has very high Social benefit and economic benefit. |
