Quick lime () acts as an excellent basic flux in extractive metallurgy. In a blast furnace, what is — s Block Elements Chemistry Question

💡 Solution & Explanation

In metallurgy, $CaO$ is a basic flux. It is added to react with non-fusible acidic gangue (impurities) such as $SiO_2$ or $P_4O_{10}$ at high temperatures, converting them into a molten, easily removable slag (like calcium silicate, $CaSiO_3$).
