How Does Limestone Help in Removing Impurities from …
Limestone, specifically calcium carbonate (CaCO₃), plays a crucial role in removing impurities from iron ore during the extraction of iron. Here are the key steps: 1. Thermal Decomposition. In the blast furnace, limestone is subjected to high temperatures, causing it to decompose into calcium oxide (CaO) and carbon dioxide (CO₂).
