The pyrrhotite samples collected from mine tailings by magnetic separation were prepared by crushing, grinding and sieving, and characterized using various analytical techniques.The rate of pyrrhotite for gaseous Hg 0 capture at 60 °C was 0.28 μg g min-1 and its capacity was 0.22 mg g-1 with the breakthrough threshold of 4%. After the magnetic separation from the mixture collected by the WESP, the spent pyrrhotite can be thermally regenerated for recycle.
