| Abstract Scope |
In this paper, the reaction behavior of sulfur in flotation desulfurization concentrate was studied. The effects of lime addition , temperature and time on the digestion rate of sulfur in the and different valence sulfur in sodium aluminate solution were investigated. Under the test conditions, with the increase of lime addition, the digestion rate of sulfur in the concentrate increases significantly, and the digestion temperature, digestion time and molecular ratio of solution have little effect on the digestion rate of sulfur.When sodium nitrate is added, the proportion of S2- in the digestion solution decreases significantly, and the sulfur content in red mud increased. The adverse effect of sulfur on the production system can be reduced by adding sodium nitrate. |
