Cement can be produced by two process,Dry processWet processBoth the process differs - grinding and mixing of raw materials in wet or dry state.
Raw materials
The materials used to make cement are,Calcareous materials (limestone)Argillaceous materials (clay)gypsumCoal dustIron oxidemagnesiumAlkalies
OPC - Ordinary Portland cementOPC - Materials used - Argillaceous and calcareous materialsPPC - Portland Pozzolona CementPPC - OPC + Pozzolonoc materials(fly ash, volcanic ash, pumicite at the time of grinding).
Grinding the raw materials (Calcareous materials and argillaceous materials)Mixing in correct proportionsBurning them in kiln at a temperature of 1300 - 15000CAt this temperature the material sinters and partially fuses to form clinkers.Clinkers are cooled and ground to a fine powder with addition of about 2-3% of gypsum.And it is weighed and packed.

The uses of an iron oxide in cement is to add color and and to give?æhardness and strength. It also helps in the fusion of raw materials during production.
For example the heating of limestone mixed with other raw materials.
Ordinary Portland cement is the most common cement used in the world, made from stucco, concrete, mortar and other materials. Slag cement is usually mixed with Portland cement and is the substance leftover after metal has been smelted from raw ore.
limestone(calcium carbonate) special type of clay gypsum and iron oxides
Factors affecting the location of cement industries include proximity to raw materials, a strong labor force, good roads and transportation. Many cement plants are built near limestone quarries or coal mines.
