It is the objective of the current project to further refine the TES process developed at FETC through bench-scale and proof-of-concept (POC) test programs. The bench-scale test program is aimed at studying the charging mechanisms associated with coal and mineral matter and improving the triboelectrification process, while the POC test program is aimed at obtaining scale-up information. The POC tests will be conducted at a throughput of 200-250 kg/hr. It is also the objective of the project to conduct a cost analysis based on the scale-up information obtained in the present work. Specific objectives of the work conducted during the current reporting period can be summarized as follows: to complete the engineering design of the TES tribocharging system and electrostatic separator, and to continue work related to the procurement and fabrication of the key components required to construct and install the proposed POC test circuit
