Advanced characterization of forms of chlorine, organic sulfur, and trace elements in available coals from operating Illinois mines. [Quarterly] technical report, September 1--November 30, 1994

PDF Version Also Available for Download.

Description

A set of 34 as-shipped coal samples from operating Illinois mines is available for this study to determine the forms of chlorine and sulfur and leachability of chlorine during wet grinding and froth flotation. The forms of chlorine may be inorganic, ionic, and organic. The forms of organic sulfur will include organic sulfide and thiophenic sulfur. Chlorine can be leached from coal during wet grinding. The potential for removal of chlorine from the samples during fine ({minus}200 mesh) and ultrafine ({minus}400 mesh) wet-grinding and during froth flotation designed primarily for removal of pyrite and ash will be determined. In addition, ... continued below

In addition, the organic/inorganic affinities of trace elements in as-shipped Illinois coals will be assessed so that the current physical coal cleaning results may be better interpreted.
