Beneficiation of Low-grade Iron Ores

1. Title of Product/Design/Equipment Beneficiation of Low-grade Iron Ores

Low-grade Iron Ores

2. IPR Status Patent/Abroad IPR Details -
3. Application/Uses  
4. Salient Technical Features including Competing Features The technology is based on processing of low-grade iron ores primarily involving washing, gravity and magnetic separation. The products are calibrated lumps, sinter and pellet-grade concentrates suitable for iron & steel making. The intermediate products are recycled towards maximization of iron recovery
5. Level/Scale of Development Pilot Scale: 1 tonne/hr
6. Environmental Considerations The process is environment friendly. No toxic/hazardous waste is discharged. Arrangement for tailings disposal is needed
7. Status of Commercialization The technology is sample specific. It is being commercialized for ore from Bolani and Gua Mines of SAIL
8. Major Raw Materials to be Utilized Low-grade iron ores.
9. Major Plant Equipment and Machinery Required Units for crushing, washing, classification, gravity and magnetic separation, dewatering.
