In a basic oxygen furnace, molten iron ore is the principal raw material and is mixed with varying quantities of steel scrap and alloys to produce different grades of steel. In an electric arc furnace, recycled steel scrap is melted directly into new steel. About 12% of our steel is made from recycled steel.

Should the pelletizing of iron ore concentrate be considered a mining or a metallurgical activity? Louis Bienvenu, Mining Engineer Ministère de l’Énergie et des Ressources naturelle. In the steel production process, there are two main steps: the extraction of iron ore and its transformation into steel. But what about pelletizing?
Iron and Steel Manufacturing Steel is manufactured by the chemical reduction of iron ore, using an integrated steel manufac-turing process or a direct reduction process. In coke making and iron making precede steel making; these steps are not necessary with an EAF. Pig iron is manufactured from sintered, pelletized, or lump iron ores us
These three steps are actually part of one general process used in smelting aluminum and other metals. The process involves taking alumina (a compound composed of aluminum and oxygen) and placing it in large carbon-lined furnaces.
Process overview. Iron ore can be upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized to be used in
Iron ore pellets and Pelletizing processes. Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-16 mm in diameter by a pelletizer and hardening the balls by firing with a

Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.
The efficiency of iron and steel production has always been decisive for producers to remain cost-competitive. It can be shown that the properties, cost and quality of iron ore are the most important factors that influence the overall efficiency of the subsequent iron- and steelmaking steps.
