Utilization of Iron Ore Tailings as Raw Material for

Mar 16, 2016 The cement industry has for some time been seeking alternative raw material for the Portland cement clinker production. The aim of this research was to investigate the possibility of utilizing iron ore tailings (IOT) to replace clay as alumina-silicate raw material for the production of Portland cement clinker. For this purpose, two kinds of clinkers were prepared: one was prepared by

Estimation of CO2 Emissions from China’s Cement

the raw materials consumed for cement production (CSI, 2005, 2011). The raw meal-based input method is often used in the United States and Japan (CSI, 2005). The clinker-based output method calculates calcination CO 2 emissions based on the volume and composition of clinker produced plus discarded dust and CO 2 emissions from organic carbon in

CEMENT RAW MATERIALS - International Cement Review

The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone. Clayey raw material accounts for between 10–15%, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity. The level
