sulphur content in iron ore concentrate

REMOVAL OF SULFUR AND PHOSPHOROUS FROM IRON ORE

The sulfur content of iron ore concentrates is generally about 0.5% to 2%, and sometimes more than 0.7%, while the permitted limit of steel industries is 0.1% (Soltanmohammadi et al., 2011). Meanwhile, the percentage of sulfur increases .

Removal of sulfur in the reduction of iron-ore

Jun 27, 2013· Abstract. In lean coal and lignite, sulfur is predominantly present as organic compounds. According to experiments with a QMC-230 mass spectrometer and an IR absorption analyzer, the removal of sulfur in the reduction of iron-ore concentrates is hindered by the adsorption of sulfur-bearing gases and its absorption by the reduced iron to form FeS, which is not reduced by carbon or

Process Mineralogy of Iranian High Sulfur Iron Ore

When the ore is further ground to 92% finer than 0.051 mm, iron concentrate of 67.12% iron grade is obtained and the sulfur content of concentrate can be reduced to 0.081%. I was also found that after further fine grinding the iron grade of iron concentrate is stable at about 67.4% and the sulfur content is continuously reduced with the decline
