BTI is continually engaged in the development of advanced fine coal preparation processes. We recently developed, patented and commercialized a unique new process used to improve the handling characteristics of fine wet coal. Known as the Mulled Coal® process, it is a simple low cost procedure that involves the addition of a specifically formulated reagent to wet fine coal by mixing the two together in a pug mill.

The converted material (Mulled Coal) offers these advantages:

• It retains most of its original surface moisture, but it handles, stores and transports like dry coal
  
• It does not cause any of the sticking, plugging, fouling, bridging and freezing problems normally associated with untreated, wet fine coal
• Unlike thermally dried coal, it will not rewet … and it is not dusty
  
  

Applications for the Mulled Coal Process

• Improve the marketability of fine coal recovered from slurry ponds
• An alternative to thermal drying
• An alternative to freeze proofing
• Conditioning the feed to pelletizers and briquetting machines
• Condition the feed to thermal dryers
