Carbon dioxide for fine coal flotation. Second and third quarterly report, December 1985-May 1986
Technical Report
·
OSTI ID:5859414
Preliminary research has demonstrated the potential for the production of superclean coal by a carbon dioxide flotation technique. In this regard, a detailed research effort on the fundamentals of coal flotation by carbon dioxide was initiated in September 1985. The first quarter of research involved sample procurement and characterization. A listing of primary coal samples being used in this research project is presented in Table 1. Initial experiments with the low-volatile bituminous coal during the first quarter included measurements of CO/sub 2/ adsorption from the gas phase, determination of the hydrophobic character by bubble attachment-time measurements, and bench-scale flotation tests. These initial research efforts have been extended during the second and third quarter. Also, in addition to the status of these research activities, progress in other areas of the research program electrokinetic behavior of coal and, FTIR spectroscopy/thermochemistry, is reported. 25 refs., 22 figs., 15 tabs.
