| titleOfInvention | Method for recovering sulfur and iron resources through reducing and decomposing titanium white waste slag green vitriol by sulfur |
| abstract | The invention discloses a method for recovering sulfur and iron resources through reducing and decomposing titanium white waste slag green vitriol by sulfur, which is characterized in that firstly, the titanium white waste slag green vitriol is dried for 5 to 40 minutes at 120 to 400 DEG C in inert atmosphere, crystal water in the titanium white waste slag is removed, then, the dried titanium white waste slag is added into a reaction vessel with the temperature being 200 to 700 DEG C, gaseous sulfur with the mold percentage being 1 to 50 percent is introduced in the reducing mixed atmosphere to take reduction reaction with the titanium white waste slag for 0.1 to 3 hours, the obtained ferrous sulfide residue is mixed with effective ingredients of ferrous sulphate in the anhydrous titanium white waste slag according to a mol ratio of 0.2 to 2:3, the materials are roasted for 0.1 to 4 hours in the weak oxidizing atmosphere at the temperature being 500 to 1000 DEG C through being uniformly ground, the generated sulfur dioxide tail gas returns the first work station, the brought heat is used for the reaction of the first work station, and the obtained solid slag materials can replace the lime for directly neutralizing the titanium white waste acid and the acid waste gas or can be used as raw materials for producing ferric oxide series pigments and for steel plants. |
