Cement Production an overview | ScienceDirect Topics
Typical raw materials used for cement production have 85% cayenne, 13% clay or blackboard, and under 1% each of materials such as silica, alumina, and iron ore. These feedstocks are crushed into particles with a diameter of less than 20 mm and mixed with a prehomogenization pile [17] .

CEMENT RAW MATERIALS International Cement Review
The UK cement industry has agreed to reduce its primary energy consumption by % per tonne of cement produced by 2010, from a 1990 baseline. In return, the industry receives an 80% rebate from the Climate Change Levy. The reductions are phased over a number of years (Table ) MINERAL PROFILE: CEMENT RAW MATERIALS 2: Extraction and processing

Deep decarbonisation of cement production | News | gasworld
In the case of ironmaking, carbon in the form of coke is used to draw oxygen out of the iron ore. Carbon dioxide (CO2) gas is the result. In cement making, calcium carbonate in the form of limestone is chemically reduced to form calcium oxide. Again, carbon dioxide is produced from the process chemistry.

Iron Ore Statistics and Information USGS
Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries.
