Metal Profile: Iron Properties and Characteristics

The iron is poured into the stacks along with coke (carbon-rich coal) and limestone (calcium carbonate). Nowadays, the iron ore normally goes through a process of sintering before entering the stack. This process forms pieces of ore that are between 10-25mm, which are then mixed with coke and limestone.

How is Iron Refined from Ore? (with pictures) -

Jul 29, 2019· Although iron does not occur in its pure form in nature, some kinds of ore contain up to 70% iron atoms. Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process.

Feb 16, 2017· Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.

Iron removal by physical chemical way -

Pourbaix diagram of Iron. However ground waters are naturally anaerobic: so iron remains in solution and therefore it is important to remove it for a water use. The elimination of the ferrous iron, by physical-chemical way, is obtained by raising the water redox potential by oxidation thanks to oxygen of the air and this by simple ventilation.
