Technology Profile
| Title: | De-ashing of High-ash Thermal Coal |
| Value Proposition: | De-ashing of the high-ash thermal coal by adopting the gravity concentration and flotation techniques. |
| Summary Application: | The technology involves treating the high-ash thermal coal for reducing the ash level by adopting the gravity concentration and flotation techniques in which the ash level can be reduced to 10-15% from a feed of 30-35% ash depending on the coal characteristics. The clean coal fines thus produced is utilised for injection in blast furnance. |
| Advantages: | The ash level can be reduced to 10-15% from a feed of 30-35% ash depending on the coal characteristics. |
| Tech. Readiness Level: |
