  • 2 Major Roles of Limestone in Cement Manufacturing

    The answer is the cement industry. Limestone plays two major roles in the cement manufacturing process, one is used as a raw material for cement clinker, and the Steel Manufacturing Sintering Process Blast Furnace ,The limestone combines with the impurities to form a liquid, which floats on top of the molten iron. This is known as slag. Basic oxygen steelmaking, or B. O. S, is the main bolt 23.3: Metallurgy of Iron and Steel Chemistry LibreTexts,Originally, the iron was collected in pools called pigs, which is the origin of the name pig iron.
