Jarosite-group minerals (AFe3(TO4)2(OH)6) typically form under acidic (pH &lt; 3.5), oxidizing, ferric and sulfate rich conditions and commonly occur in the oxidized portion of sulfide deposits, hydrometallurgical wastes, acid sulfate soils and environments contaminated by acid rock or acid mine drainage. Jarositic wastes are typically stored in disposal ponds under circum-neutral conditions, thereby rendering the mineral phase unstable and susceptible to reductive dissolution through Fe(III) re
