Title:

Beneficiation of Low-grade Iron Ores

Value Proposition:

Production of  Low-grade iron ores through technology involving washing, gravity, magnetic separation and finally recycling for maximum recovery.

Summary Application:

The processing of low-grade iron ores involves washing, gravity,magnetic separation after which the products are calibrated lumps, sinter and pellet-grade concentrates for application in iron & steel making. For maximum recovery the intermediates are recycled.Arrangement for tailings disposal is needed. The technology have its application in iron and steel making.

Advantages:
  • The process is environment friendly.
  • No toxic/hazardous waste is discharged
  • The intermediate products are recycled towards maximization of iron recovery
Commercialization Status: Already Commercialised
