Elemental Analysis of Steel, Iron Ore and Cast Iron

For iron samples, usually no sample preparation (e.g. cleaning) is required immediately before starting a carbon or sulfur analysis. It is important that samples taken during cast iron production or pig iron samples should not be treated with acetone or any other organic solvent, because this could alter the distribution of graphite and iron

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

[PDF] Reduction of Sulphur Content of AGBAJA Iron Ore

Iron ores are used in blast furnace for the production of pig iron; AGBAJA Iron ore has an estimated reserve of over I billion metric tonnes. Unfortunately, this large reserve cannot be utilized for the production of pig iron due to its high sulphur contents. This work studied the reduction of sulphur content of AGBAJA iron ore. Acid leaching methods were used to reduce sulphur contents of the
