Cement Raw Materials International Cement Review. 2.1 Extraction The raw materials used in cement manufacture are extracted in large quarries, typically with outputs of up to, or over, 2.5 million tonnes per year. Typically about 1.65 tonnes of limestone 1.5 to 1.8 tonnes and 0.4 tonnes of clay are quarried for each tonne of cement produced.Sand and gravel quarries are pumped to allow them to be worked dry or operated as lakes with extraction below water. A conveyor draws raw material into the processing plant, where it is washed to remove unwanted clay and to separate sand. Sand separated during processing is dewatered and stockpiled. Gravel then passes over a series of screens ...
