Hydrometallurgical decomposition of pyrite and marcasite

Hydrometallurgical decomposition of pyrite and marcasite

Jun 01, 2002 For marcasite, when HNO 3 concentration was 1 M, only 18% of the marcasite was decomposed in 10 min. With an increase in HNO 3 concentration to 3 M, marcasite could be approximately fully decomposed in the same leaching time.. When compared to pyrite, it was demonstrated that marcasite was much more readily decomposed in the experimental conditions.

Apr 26, 2021 Marcasite is only stable at low pH ( 5) conditions (Murowchick and Barnes, 1986), and hence we propose that the pyrite-marcasite alternations, as observed at Paleochori Bay may be the result of the periodic discharge of lower pH vapor-dominated fluids (cf. Pichler et al., 1999), causing the precipitation of marcasite instead of pyrite.
