In this process, lime is first slaked and converted to calcium hydroxide (Ca(OH) 2). Next, the lime slurry is combined with soda ash (Ca(OH) 2) + Na 2 CO 3). This yields caustic soda and limestone (2NaOH + CaCO 3). The limestone from this reaction can be recycled to make lime, which can then be reused for other purposes.
To create an even purer form of iron, known as pig iron, limestone must be added to the mix and the heat increased. This is done contemporarily in the silo-like structure known as a blast furnace. The calcium in limestone bonds with the silicates in the ore, creating a material called slag, which floats on top of the pure liquid iron. The iron ...
