Chapter 2 - GARDGuide

The most common sulphide mineral is pyrite [FeS 2]. Pyrite is the mineral of most relevance from an acid-generation perspective, because its concentration, grain size, and distribution may be the most important factors affecting the production of acidic mine waters (Nordstrom and Alpers, 1999).

Structures of Mineral Deposits

Mineral deposits formed as a consequence of sedimentary processes. Structural deformation may alter the form and attitude of some of these deposits. Lenticular masses, veins, lodes and zones of disseminated mineralization result from metamorphic processes. Recognition of the environment and existence of potentially economic mineral deposits may be based upon a variety of geological criteria:

When chalcopyrite and pyrite are mixed in different proportions, the formation of H2O2 was seen to increase with increasing pyrite fraction in the mixed composition. The results of H2O2 formation in pulp liquid of chalcopyrite and together with pyrite at different experimental conditions have been explained by Eh-pH diagrams of these minerals.
