When iron ore is reduced in a blast furnace, some of the S i O 2 impurity is also reduced by reaction with carbon to give elemental silicon and carbon monoxide. The silicon is subsequently reoxidised in basic oxygen process, and the resulting S i O 2 reacts with C a O, yielding slag.What is the formula of slag
