Evaluation of column flotation for fine coal cleaning at the Lady Dunn Preparation Plant
- Entech Global, Inc., Golden, CO (United States)
In 1992, Pittsburgh Energy Technology Center (PETC) of the Department of Energy (DOE) awarded a cost-sharing contract to a team headed by Amax R&D Inc. The contract was to develop advanced cleaning technologies for production of low-ash, premium fuel from coal. Entech Global of Golden, Colorado, now manages this contract for Amex R&D, and Cyprus Amex Coal Company, Arcanum, Bechtel, University of Kentucky and Virginia Tech are among the team members. Two advanced technologies were selected for development, column flotation and selective agglomeration. Even though production of premium fuel is the primary goal of the project, the DOE asked that near-term applications of these advanced technologies be investigated as well in order to learn how they might be used to recover coal now being discarded from existing preparation plants as fine refuse The resulting investigation of near-term applications began with an engineering analysis or paper study of potential applications at Amax Coal operations. The project continued with further laboratory and bench-scale process development and culminated with the installation of a pilot-scale advanced flotation column at the Lady Dunn Preparation Plant. The results of this cooperation between the Department of Energy and the coal industry are described in this presentation.
