Engineering Evaluation / Fact Sheet

The raw coal is either sent directly to the plant dump bins and conveyed to a raw coal silo or stores in a raw coal stockpile. Once the coal is conveyed to the plant, the material is broken and sized via mechanical and wet washing systems. Refuse material is removed by gravity and mechanical separation, and ultimately sent to the refuse area for
