Other secondary metallurgical slag (Slag Steelmaking - SMS) Most of the slag resulting from the integral cycle is generated during the production of pig iron and is classifiable as "by-product" and can be used for the production of cement named Granulated Blast Furnace Cement.
Slag Recycling. With high-quality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 0.25 to 0.30 t of slag per t of pig iron. In the case of inferior grade ores below 60 %, the amount of slag is typically 0.35 to 0.50 slag/t of pig iron [1]. 3958; Iron Ore Slag Recycling And Metals Recovery

Ductile Iron, namely high purity iron units, Ductile Iron returns and steel scrap, on the formation of slag, independently of other sources of slag such as Mg treatment. By knowing the individual impact of each charge material on slag
ductile iron production has experienced continued growth, the quality of metallic scrap and other iron-unit feed stocks has steadily deteriorated. The result: slag related melting problems have become
slag industry. Additionally, slag is a sustainable (green) material that can be reclaimed and reused multiple times. Using iron and steel furnace slag will help preserve our natural resources. Based on numerous environmental tests, studies and reviews by governmental agencies and the iron and steel industry, we know that iron and steel slag is a

Use of iron and steel slag in place of mined and quarried rock and mineral aggregates saves these natural resources and reduces impact on the environment. Blast furnace slag is used in cement manufacturing, asphalt mixes, glass manufacturing, precast concrete, wallboard, mineral wool and sub-base for road and interstate highway construction.
internal recycling loop of iron scrap (e.g., skulls, spills, entrapment in slags) corresponding to between 1 and 2% of production, or 750,000 net tons, in 1999.
