disposal of slag from blast furnace

Slag recycling - recoveryFig. 6 shows the recycling of blast furnace slag for 2018. The production volume was 20.7 Mta, of which 86.0 % was sand slag from slag granulation and 14 % was air-cooled BFS. From interim storage, 1.5 Mta was added to the production quantities, so that a total of 22.3 Mta of BFS was used in 2018. 17.9 Mta went into the production of cement and ...Slag Cement - Lehigh Hanson, Inc.Recycling an Industrial Byproduct. Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag.
