Hydrocarbon-oil encapsulate bubble flotation of fine coal. Technical progress report for the thirteenth quarter, October 1--December 30, 1993
- West Virginia Univ., Morgantown, WV (United States). Dept. of Mineral Processing Engineering
Gasified collector and liquid collector addition techniques were applied in the column flotation to demonstrate the selectivity of utilizing the hydrocarbon-oil encapsulated air bubbles in the fine coal flotation process. A 3-in. flotation column was used to evaluate two modes of collector dispersion and addition techniques on the recovery and grade of fine coals using various ranks of coal. Five different coal samples were used in the column flotation test program. They are Mammoth, Lower Kittanning, Upper Freeport, Pittsburgh No. 8, and Illinois No. 6 seam coals, which correspond to anthracite-, low volatile-, medium volatile-, and high volatile-seam coals, respectively. In this quarterly report, the test results for the Illinois No. 6 seam coal are reported.
