Cast iron. The molten iron from the bottom of the furnace can be used as cast iron. Cast iron is very runny when it is molten and doesn't shrink much when it solidifies. It is therefore ideal for making castings - hence its name. However, it is very impure, containing about 4% of carbon. This carbon makes it very hard, but also very brittle.
The process of extracting iron ore involves mining, where large-scale excavation is carried out to access the ore deposits deep within the earth. Once the iron ore is extracted, it undergoes a series of processing steps to remove impurities and prepare it for further use. The first step in this process is crushing and grinding the ore to …
