Abstract

Pyrite/marcasite size category, form, and microlithotype association were examined in the feed, clean, and refuse coals from 14 western Kentucky preparation plants. The feed coals are high in sulfur and a relatively large amount of pyritic sulfur remains in the clean products. Pyrite in the clean coals was generally less than 10 micrometers in diameter. Pyrite forms concentrated in the clean coals were frequently framboidal and euhedral types associated with vitrite and clarite. The refuse concentrated the coarser massive and cleat forms associated with carbominerite.
