Control of acid mine drainage: proceedings of a technology transfer seminar. Pittsburgh, PA: U.S. Department of the Interior, Bureau of Mines, IC 9027, 1985 Jan; :3-11
Although Bureau of Mines research into pyrite reactivity is still in preliminary stages, it can be concluded that: 1. Pyritic and sulfate sulfur in noncarbonaceous materials can be differentiated using a Leco SC-32 Sulfur Analyzer. 2. Pyritic sulfur can be quantitatively determined in noncarbonaceous matrices using evolved-gas analysis techniques. 3. Framboidal and isolated euhedral pyrite morphologies differ significantly in thermal reactivity. 4. Carbonaceous materials seriously interfere with the evaluation of sulfur species using evolved-gas analysis.
