Abstract
The report pertains to at-source control of pyrite oxidation. The current level of knowledge of acid mine drainage formation is critically reviewed, with emphasis on reaction kinetics and reactant and product transport. A reaction system model is developed which provides a conceptual framework for subsequent discussion dealing specifically with the physical, chemical, and biological characteristics of pyritic systems encountered in mining situations. Practical considerations of at-source control of acid mine drainage formation in underground mines, spoil banks, and refuse piles are presented. Deficiencies in current knowledge include: Descriptions of the physical environment existing at pyrite oxidation sites in natural systems are far more incomplete that the current understanding of pyrite oxidation kinetics; Oxygen transport is poorly described at this time, but is probably the rate-controlling factor in most instances; Serious questions exist as to the effectiveness of air-sealing techniques as currently practiced; The significance of bacterial catalysis of pyrite oxidation under field conditions has not been established.
