5. Chemical Applications. Limestone's chemical properties allow it to bond to sulfur dioxide and silica. For this reason, it is used in fuel gas desulfurization to remove toxic emissions from fossil-fuel power plants, remove impurities from iron, and control the viscosity of glass during glassmaking.
