Recovery of iron from a high-sulfur and low-grade iron ore
Apr 10, 2018· 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.

Process Mineralogy of Iranian High Sulfur Iron Ore
Processing of Iranian high sulfur iron ore is problematic in minerals industry. The iron ores were studied by the means of polarizing microscopy, chemical analysis, X-ray diffraction. The study shows that the iron ores have high grade of iron, and complex structures. XRD showed that the iron ore consists of metallic minerals such as magnetite with a small amount of hematite and limonite and

Recovery of Iron from a High Phosphorus and Sulphur Iron
In this study, an iron ore was investigated with high content of phosphorus and sulphur about 1.09% and 1.4%, respectively. The grade of Fe is about 30%, which is mainly composed of siderite, about 23.40% of iron is existed in the form of silicate, such as chlorite, canbyite, and a small amount of pyrite, magnetite. The phosphorous mainly occurred as apatite, which is close united with the

Study on Bioleaching of Sulfur in Iron Ore by Mixed
Compared with original sample, sulfur content decreased 95.06%, iron grade increased by 9.25%, and iron recovery was 94.13%. From the results it can be concluded that this microbial process for high sulfur iron ore lead to a significant effect of sulfur reduction and substantial increase in iron grade.

Different Types of Iron Ore 911metallurgist
The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite. Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron. It is of valuable composition, carries only 14 or 15% of iron, and is used more for
