lead zinc ore low intensity magnetic separation
Desulfurization Mechanism of Lead–Zinc-Bearing …
The impurity sulfur in lead–zinc-bearing hematite–limonite ore mainly exists in the form of galena, sphalerite, pyrite, and natural sulfur, and deep reduc-tion roasting–low intensity magnetic separation does not effectively remove sulfur in a low valence state, which affects the quality of iron ore concentrate.
