 Technology Profile

Title:

Technology for Dry Beneficiation of Non-coking Coal for Application in Thermal Power and DRI

Value Proposition:

Ash reduction in high ash non-coking coal by dry processing for use in thermal power and Direct Reduced Iron application and De-shaling of high ash non-coking coal.

Summary Application:
  • Producing clean coal with 34% and 25% ash with high yield
  • No need for process water
  • Prevents the generation of coal slime water
  • Requires relatively less floor area compared to conventional wet processing
  • Less power consumption per ton of coal compared to the wet processing of coal
Advantages:

The process conserves water, no process water generated which prevents water pollution. Also, technology is gained a good market in thermal power and directly reduced iron applications.
