How Cement Is Made
Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high ...

Effect of adding limestone on the metallurgical properties of iron ore
The amount of liquid formed in the sintering process of iron ore pellets must be high enough to bond the pellet, ... The higher porosity in the fluxed pellets is due to the decomposition of limestone in the sintering process. Limestone fluxed pellets are highly porous and therefore very reducible but physically weaker than non-fluxed ones.
