Pyrite oxidation is a complex hydrobiogeochemical process that accounts for about 11% of the sulfate found in river drainages (Berner and Berner, 1996), although these estimates do not include large flows of AMD from Rio Tinto and Odiel Basins to the ocean (Nieto et al., 2007). Mining activities have increased the rate of pyrite oxidation and ...
Pyrite. Pyrite, or iron pyrite, also known as fool''s gold, is an iron disulfide mineral containing iron and sulfur. The name fool''s gold comes from novice prospectors commonly mistaking it for gold. Pyrite has a brassy sheen, and unlike gold which is malleable, pyrite will crush into a brown powder.
2000-7-4 · The oxidation of pyrite is an exothermic process. If pyrite oxidation occurs in enclosed systems, such as underground mine galleries or in waste piles, the dissipation of the heat released by the oxidation process is often inefficient and, as a result, the temperature in the system rises.[33, 34] For example, temperatures in an abandoned mine ...
