Maximization of Iron Recovery from Lean/Low Grade Iron Ore Resources by
Reduction Roasting Technique

Advantages / Salient Technical Features Scale of Development
• It reduces the consumption of ore by producing more • Pilot Scale Level (Current TRL Level : 07)
yields. Hence, it enhances the conservation of the
ore. Commercialization Status
• It reduces the environmental impact by utilizing the • Yet to be commercialized
low grade ores.
• It improves economical benefit to the industry.
• It reduces the technological problem in downstream Techno-economics
industries. • Reduces the technological problem in
downstream industries and improves
economical benefit to the industry
Problem being addressed
• When conventional beneficiation is not feasible Technology Package
for beneficiation of the low and lean grade iron
ore resources, the reduction roasting process is an • Process flowsheet development
alternative route.
