Summary:
The coal from IB-Valley Area is generally of moderate to high ash (F grade), supplied raw to power plants. There is no dedicated washery at the mine site. However, MCL was constructed a central 10 MTPA coal washery in Ib Valley (located in Lakhanpur Area), which will wash coal from the IB Valley Coalfield to improve quality for customers. This washery, once commissioned, could treat part of Samleswari’s output (as Samleswari produces a large volume of coal that might benefit from washing to reduce ash). Moreover, a common Coal Handling Plant (CHP) with crushing/sizing facilities exists in the area to ensure dispatch coal meets size specifications (<100 mm). Both mines have mobile crushers and feeder breakers at pit head.
