Development of the chemical and electrochemical coal cleaning process
Liberation studies on the Elkhorn No. 3 coal were completed in this quarter. The results obtained from the 65 {times} 150 mesh samples showed that the amount of mineral matter and pyrite liberated by the Chemical and Electrochemical Coal Cleaning (CECC) process increases with time. The free mineral matter undergoes some reduction in size during the CECC treatment and the majority of the liberated mineral particles in this sample are finer than 150 mesh. This is opposite that found for the Pittsburgh No. 8 coal, which may explain the better response of the Elkhorn No. 3 coal to CECC treatment. The continuous bench-scale unit was modified during the quarter to satisfy the health and safety requirements of the university. The unit was modified to ensure that any spill or leakage can be contained. Due to these modifications, continuous testing work was delayed.
