If the limestone was not added, iron silicate would be formed and metallic iron would be lost. Adding limestone also has the advantage of reducing the temperature required to melt the iron, so saving on energy. Although slag is a waste product of the iron and steel industry, it can be turned into 'slag cement' and used to make roads.
