TL;DR: This study observed the formation of a mechanically 'strong' coating on pyrite that suppressed the mineral's oxidation, and found that As mobility under acidic conditions was limited by its precipitation as ferric arsenate, scorodite, or a Fe/Al arsenate phase, including its strong adsorption to Fe-oxyhydroxides/oxides.
