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 other is used as a cement admixture. Limestone is one of the key raw materials of cement clinker. Around 80-90% of the raw material for the kiln feed is limestone.Web

Steel Production
The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the ...Web
