The Pennsylvania-based material processing and environmental services company, Harsco Corporation, has signed a multiyear contract to provide onsite material services to Jindal Stainless, which is India’s largest stainless steel producer.
The deal marks Harsco’s fifth major steel mill services site in India and its first serving India’s stainless sector. Harsco’s services include specialized process technologies for recovering metal from stainless steel slag co-products at JSL’s Jajpur, Odisha, India, facility, where Harsco has consistently generated metal recovery rates greater than 99 percent at similar operations throughout the world.
“From 1 million metric tons per year of stainless steel production, we used to lose 5-6 thousand metric tons of metal embedded in slag,” says S. K. Agrawal, JSL’s unit head. “With this new setup, Harsco will handle all slag, treat it to recover metal and generate a metal-free slag.”
The metal content recovered by Harsco will be immediately available for reuse in the production of new steel, while Harsco will develop a number of commercial products from the residual slag material. The slag material, which ranges from agricultural fertilizers to construction materials, is expected to offer a number of commercial applications that will provide Harsco’s customers with a near-zero waste stream alternative to landfilling the material.
