Occurrence and Release of Trace Elements in Pyrite-Rich ...

Waste rock can contain high concentrations of deleterious trace elements, which upon oxidation can be released, having a significant impact on water quality. Therefore, knowledge about their occurrence and overall mobility is crucial to ensure suitable environmental protection measures. Sulfide-rich waste rock was characterized and quantified using automated mineralogy (QEMSCAN).

Pyrite: The Real Story Behind "Fool''s Gold"

 · Pyrite: The Real Story Behind "Fool''s Gold". Pyrite is called "Fool''s Gold" because it resembles gold to the untrained eye. While pyrite has a brass-yellow color and metallic luster similar to gold, pyrite is brittle and will break rather than bend as gold does. Gold leaves a yellow streak, while pyrite''s streak is brownish black.
