  Experimental Study on Desulfurization and Ceramic Tile …

  Desulfurization and ceramic tile preparation of gold cyanide tailing have been carried out. A novel oxidant DDTQ has been successfully applied to collaborative decyanation and desulfurization. The removal efficiency of cyanide ions can exceed 99%, and the reduction rate of pyrite and chalcopyrite can be achieved above 90% at the same time with wet …

  201747 · The titanium ore addition improved the desulfurization performance of the AC-Tit effectively; the highest sulfur capacity was 203.3 mg/g, which was much higher than that of the blank sample (120.1 mg/g). After desulfurization, some metal sulfates, i.e., Fe2(SO4)3 and CaSO4, were detected on the AC-Tit samples.

  Desulfurization Mechanism of Lead–Zinc-Bearing Hematite–Limonite Ore ...

  202463 · The impurity sulfur in lead–zinc-bearing hematite–limonite ore mainly exists in the form of galena, sphalerite, pyrite, and natural sulfur, and deep reduction roasting–low intensity magnetic separation does not effectively remove sulfur in a low valence state, which affects the quality of iron ore concentrate. Thereby, the desulfurization mechanism of the …
