Recovery of iron from a high-sulfur and low-grade

2018-4-10  High-sulfur iron ore was grinded and sieved through 50 mesh screen (300 μm opening). Iron and sulfur contents of dried powder were determined by chemical methods, because XRF analysis is not accurate for sulfur containing ores. The results showed that the ore contains 47% Fe and 24% S.
