Production of Ferronickel from Chromite Overburden
Advantages / Salient Technical Features Application/Uses
• Efficient utilisation of Chromite Overburden (COB), a • For stainless steelmaking and special
mining waste, to produce value-based product (Fe- steelmaking
Ni, Fe-Cr)
• Fe-Ni as an import substitute Scale of Development
• Technology demonstration (Current TRL
Level : 04)
Problem being addressed
• Demonstration of recovery and extraction of nickel Commercialization Status
from COB by pyrometallurgical techniques • Yet to be commercialised
Environmental Considerations (if any) Techno-economics
• Utilisation of COB which otherwise pollutes the soil • To be estimated after pilot scale study
and environment
Technology Package
Major Raw Materials to be Utilized • Development of technical flow sheet
• Utilisation of COB, a waste material
IPR Status / Details (India/Abroad)
