CHEMICAL GRADE LIMESTONE Carmeuse
2021-11-18 Our chemical grade limestone is used in the ironmaking process to produce the slag, which removes impurities from the iron ore while making liquid pig iron. Limestone is added to iron sinter and pellets to add flux and promote agglomeration in your products. Blast furnaces can add limestone directly to the burden to promote slag formation and protect the refractory.
