Fundamental research on surface science of coal in support of physical beneficiation of coal: Quarterly report No. 3, April 1--June 30, 1988
A research grade microscope and two glove boxes for oxygen-free operations have been acquired. Contact angle measurements on Kentucky No. 9 coal have been consistent with those made in the previous quarter, with oil/water contact angles in the range of 35 to 38/degree/ measured through the oil, for coal, and about 80/degree/ for iron pyrite. Adsorption measurements on Upper Freeport coal with 0.2% octanol in decane reveal that at this concentration, the octanol adsorbs only on the external surface and covers more than half of a monolayer area. These adsorption measurements will be used to correlate with the contact angle measurements. Scanning electron microscopy was used in identifying the highly reflective inclusions in coal, as pyrite and the thin white sections as calcium carbonate. 1 fig., 1 tab.
