The iron ore desulfurization process of pyrrhotite, pyrite-associated iron ore, includes grinding, desulfurization, magnetic separation-flotation combined desulfurization process, and roasting-magnetic separation-flotation combined desulfurization process.
Desulfurization by flotation produces sulfide-lean tailings, which can be used as cover materials, and sulfide-rich concentrates, which may contain valuable sulfide-associated metals such as gold.
A straightforward alternative to iron ore desulfurization involves acid leaching, where the reduction of sulfur content is directly proportional to H 2 SO 4 concentration and reaction time, while inversely related to particle size.
Therefore, for iron ore with low sulfur content, the nitrogen atmosphere can be tried. Compared with iron ore with higher sulfur content, better desulfurization efficiency is obtained by oxidizing roasting.
In the ultrasonic combined with microwave enhanced microbial desulfurization of sulfide ore, ultrasonic power had the greatest effect on the microbial desulfurization of sulfide ore, followed by microwave power and microwave reaction time, while ultrasonic reaction time had the least effect. 4.3.
