cement plants are located close to a calcareous raw material source whenever possible. Other elements included in the raw mix are silicon, aluminum, and iron. These materials are obtained from ores and minerals such as sand, shale, clay, and iron ore. Again, these materials are most commonly from open-pit quarries or mines, but they …Web

Cement plants are highly capital intensive. The construction of new plant costs about £10 million for each 100 000 tonnes per year of cement capacity. Large modern plants can, therefore, cost over £100 million. Ongoing capital investment at individual plants can also typically amount to several million pounds a year.Web
