All of the iron and steel plants in Oman are employing either direct reduced iron (DRI) or electric arc furnace (EAF) production processes. The advantage of using the DRI process to transform ore into pig iron, is that it can use either natural gas or coal as a feedstock. DRI smelting is also an attractive choice

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.

In this process, iron ore, coke (a form of carbon), and limestone are fed into the furnace, where intense heat and chemical reactions extract molten iron. Innovations in blast furnace technology, including hot blast systems, oxygen enrichment, and refractory materials, have significantly improved productivity and environmental performance.

Aluminum (Al) is present in clays, micas, and feldspars in some iron ore deposits and in limestone flux used in steel making. Small amounts of Al (< 1%) can increase the viscosity of the slag, which impedes the operation of the furnace. Sulfur (S) can be present as sulfides in iron ore and the coal used in the smelting process. At ...
