Low Ash Coal Production for Utilization in Metallurgical Industries
Advantages / Salient Technical Features Scale of Development
• It is easily possible to achieve 10% ash coal with • Lab validation (Current TRL Level : 05)
reasonable yield with feed ash less than 30%.
• Can be utilized in Blast furnace injection / DRI and Commercialization Status
other metallurgical purpose ROI within 3 years. • Ready for commercialization
Problem being addressed Technology Package
• Beneficiation of low grade coal for utilization in the • Commercial process flowsheet
metallurgical industries.
Environmental Considerations (if any)
• Environment Friendly
Major Raw Materials to be Utilized
• Low ash coal, coking coal, non-coking coal
IPR Status / Details (India/Abroad)
• NA
Application/Uses
• Can help in recovering carbon value from high ash
Indian coking and non-coking coal rejects/fines/
slimes
• The quality of the coal indicates that it can be used
for metallurgical purposes even in blast furnace
injections.
• The carbon value can be recovered from coal washery
slimes by flotation process to achieve less than 10%
ash coal.
