About

Increasing the utility of steel scrap through innovation in sorting and impurity removal will increase the use of secondary feedstock and achieve cost parity for secondary materials for steel products. This study will investigate: 1) physical methods such as optical sorting to upgrade scrap steel and 2) chemical or metallurgical treatment methods to remove or neutralize the effect of impurities in molten steel.
