Rich iron ore contains more than 57 % iron, less than 8–10 % silica, less than 0.15 % sulphur and phosphorus. It is a product of natural enrichment of banded iron formations originated by leaching quartz and decomposition of silicates during long-term weathering or metamorphosis. Lean iron ores may contain 26 % iron min.

For low-grade iron ore, smelting costs and resource wastage will be increased. Product quality of such ore is affected adversely by an excessive amount of sulfur. This also causes environmental pollution.

The roasted ore leaves through the bottom brick hearth and sulfur dioxide (2-6 percent) exits through the top. Smelting – Smelting involves the application of heat to a charge of copper ore concentrate, scrap, and flux to fuse the ore and allow the separation of copper from iron and other impurities. The smelter furnace produces two separate ...

Sulfur (S) can be present as sulfides in iron ore and the coal used in the smelting process. At concentrations > 300 ppm, S causes brittleness in hot iron and iron cannot be used in steel making. Modern steelmakers add manganese (Mn) in proportion to the S …

per year. The minerals in the iron ore are mainly of magnetite and hematite, but many of the iron ore rocks and mines contain sulfide minerals such as pyrite, chalcopyrite, arsenopyrite, etc. 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

This document specifies a combustion/infrared method, using a high-frequency induction furnace, for the determination of the sulfur content of iron ores. This method is applicable to sulfur contents between 0,002 % (mass fraction) and 0,25 % (mass fraction) in natural iron ores, iron ore concentrates and agglomerates, including sinter products.

Following a series of beneficiation tests, it could be shown that the iron content in the final concentrate of the Egyptian iron ore would be significantly below 58%, which meant that the ore could only be sintered or pelletized for use in blast furnace ironmaking and that it could not be feasibly used in a direct-reduction process route.

On the other hand processing of iron ore with higher Phosphor levels brings significant economic benefits due to the low price of such ore compared to high quality ore low in Phosphor; same can be said for coal high in Sulfur. To master these challenges hot metal treatment processes have been developed.
