 · Most of the BF liquid slag gets granulated and is sold to cement manufacturers for the manufacture of BF slag cement. A small amount of BF slag gets air cooled. The air cooled BF slag is either dumped as landfills or used in road repairs within the steel plant. In either case the iron contamination of the slag is separated and sold for remelting. Flue dust and GCP dry dust (in case of dry .

In the cement manufacturing sector, the kiln process uses 90 percent of the energy used and can be expected to have the largest impact on the plantlevel EEI. Although cement plants have a high EEI benchmark (85) for the kiln process, it is important to prioritize efforts in this area because a small improvement in the kiln process can potentially result in a large reduction in energy use.
