Recovery of iron from a high-sulfur and low-grade iron ore 10.04.2018 Iron and sulfur contents of dried powder were determined by stone methods, because XRF analysis is not accurate for sulfur containing ores. The results showed that the ore contains 47% Fe and 24% S. This quantitative analysis indicates that the ore
how to reduce sulphur from iron ore
Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

Sulphur removal in ironmaking and oxygen steelmaking
For sulphur removal a low oxygen activity and a basic slag are required. In the BF typically 90% of the sulphur is removed; still, the HM contains about 0.03% of sulphur. Different HM desulphurisation processes are used worldwide. With co-injection or the Kanbara reactor, sulphur concen trations below 0.001% are reached. Basic slag helps desulphurisation in the converter. However, sulphur
