The raw materials mix or "charge" enters the furnace from the top and hot air is blown or blasted from the bottom causing the coke to burn and the oxygen to combine with carbon in the coke to form carbon monoxide. Now, this carbon monoxide that is unstable, reacts with the ore to form carbon dioxide and iron. The Separation Of Iron.

Metallurgy Iron, Steel, Alloy: From 1500 to the 20th century, metallurgical development was still largely concerned with improved technology in the manufacture of iron and steel. In England, the gradual exhaustion of timber led first to prohibitions on cutting of wood for charcoal and eventually to the introduction of coke, derived from coal, as a more efficient fuel.

Iron is extracted in the form of metallic iron (Fe) by reducing the oxide ores with a reducing agent. The principal agents commonly employed to serve this reduction process are the naturally occurring forms of carbon such as coke, charcoal and coal. In order to extract the iron, Fe (5560%)rich ore is usually used.

See Answer. Question: Iron ores are rocks from which metallic iron can be extracted for steel production. This process involves several steps. Iron ore is first mined and then turned into pig iron in a blast furnace, and some rock waste such as silicon dioxide is separated out. In the final step, the pig iron is refined into steel using a ...

In the HPSR process, the type of iron ore or ironcontaining residuals affects ore reduction by hydrogen. The process eliminates the prior agglomeration process, and iron ore fines can be directly introduced. The process is compared with fluidized bed reduction, which uses hydrogen as a reducing agent and fine ore as feed material.

More carbon reacted with the ore and produced a cast iron rather than solid iron. Also, the slag produced was less rich in iron. A different process was used to make "tapped" slag. Here, only charcoal was added to the furnace. It reacted with oxygen, and generated carbon monoxide, which reduced the iron ore to iron metal. The liquefied slag ...
