CSIR-IMMT/MAT - 11

Production of phosphorous-free Chrome Ore pellets of high compressive strength

Advantages / Salient Technical Features IPR Status / Details (India/Abroad)

• It is superior to the conventional briquette making • Process knowhow; Patent is in the drafting
process of treating Cr ore fines with molasses as a stage
binder.
• It was observed that the compressive strength of Application/Uses
CSIR-IMMT pellets is around 2.5 times higher than • For ferrochrome making and stainless
that of China pellets and around 3 times more than steelmaking
that of South Africa pellets that are being currently
imported. Scale of Development
• Technology demonstration (Current TRL
• The Cr pellets made are phosphorous free. Level : 04)

Problem being addressed Commercialization Status
• Production of phosphorous-free Cr ore pellets which • Yet to be commercialised
otherwise is detrimental to steel making
• Showcasing pelletisation as a promising way to tackle Techno-economics
Cr ore fines in place of briquetting • Techno-economic feasibility study has been
estimated
Environmental Considerations (if any)
• Efficient utilization of Cr ore fines which otherwise Technology Package
cause environmental hazards • Development of technical flow sheet

Major Raw Materials to be Utilized
• Utilisation of Cr ore fines
