The Relationship Between the Thermal Activity of Pyrite and the Rate of Acid Generation.
The thermal reactivity of pyrite in 33 overburden samples was evaluated by evolved gas analysis (ega). Eight samples contained carbonaceous material; large exothermic effects resulting from the combustion of this material rendered ega thermograms from these samples meaningless. Ega techniques and instrumentation capable of evaluating carbonaceous samples have been developed but were not available for this study. Therefore, the results of this study are based on 25 noncarbonaceous overburden samples.
