 Nickel & Chromium From Stainless Steel Pickling Bath Sludge

(1) The process consists of selective separation of Chromium from the sludge and converting the Chromium -free sludge to ferro nickel. The process recovers above 95% of Ni & Cr. (2) Nickel and Chromium are used as alloying elements in making of alloy steels.

Area: Engineering Sciences

Funding agency: Department of Science and Technology (DST), Govt. of India

Benefits: The innovation improves Nickel and Chromium recovery from the sludge.

Implementing institute: National Research Development Corporation (NRDC), Govt. of India
