Iron Extraction: The Process Of Iron Extraction
Iron Extraction
What is Iron extraction?
Iron extraction is a process Iron (metal) is extracted from iron ore, also called as hematite, in the container. It uses blast furnace to extract iron. Iron is extracted through the process of reduction with carbon or carbon dioxide. This raw material, iron ore, contains iron oxide, and this is a compound that is containing iron. Other raw materials, such as coke, limestone, and air are required, and they contain carbon, calcium carbonate, and oxygen in order. Coke helps this process by burning coal in the air, for producing heat, then reacts with carbon monoxide and the iron oxide. Limestone reacts with acidic impurities to structure molten slag from iron. Air helps allowing coke to burn, so it can produce heat and carbon monoxide.
How does it work?
Blast furnace is a smelting metallurgical furnace, that has a form of tower about 25-35m high, used for produce of industrial metals from below. Through top of this huge container, iron ore, coke, and limestone goes into the blast furnace. As they are included, coke acts as reducing agent, supporting iron oxide. And carbon is released and contact with iron ore, starts reducing the iron oxide. So, the formula comes here, 2Fe2O3 + 3C 4Fe + 3CO2 (iron oxide + carbon iron + carbon dioxide) In this step, iron oxide is reduced to iron, and the carbon is oxidized and becomes carbon dioxide (C + O2 CO2) After that, when carbon dioxide reacts with hot coke, it creates carbon monoxide (CO2 +

Once the burning was officially over, the crucible was placed onto a ceramic tile to cool off. Next the charcoal and copper material were poured onto a paper towel and were separated from carefully distinguishing them one from the other. Then comparisons were down through analysis of the copper (II) oxide smelted.

Also, because the factory is next to water, it can be assumed that the factory has dumped into this water, causing it also to become polluted”(Document 3). Yes, wonderful products came from these factories; things like clothing and cars, but coal was being used to power these machines that produced. Black coal ash rose up into the sky and was being breathed in by the people and animals. Coal is not the best thing for people’s lungs.
