Pyrite oxidation is an important process controlling groundwater composition, but little is known about the conceptualization of this mechanism for the modelling purposes. Few examples of analytical calculations and numerical simulations have been presented in the paper. The examples concern the processes of pyrite oxidation by oxygen and nitrate both in unsaturated and saturated zones in case when carbonate minerals do not occur. The Fick's first law has been adopted in the evaluation of oxygen transport through unsaturated zone. The numerical simulations were performed by using Phreeqc and Phast codes with the assumption of a local equilibrium approach. These codes have proven to be powerful tools to analyze and quantify the reaction controls and the coupling between transport and processes of pyrite oxidation.
