Spain has a long mining tradition dating from pre-historic times up to the present day. The cessation of mining activity has generated a large amount of mine wastes, most of which represent geochemical hazards. Mine tailings are watery sludge composed of medium-to-fine-grained material, resulting from grinding and mineral processing (e.g., galena, pyrite, sphalerite, and arsenopyrite).
In this study, batch experiments were performed using a number of iron ore samples from Chilean and Swedish mines and a mine tailings sample. The goal was to study the extent and kinetics of magnetite bioreduction under marine conditions and the potential release of trace elements.
