The sulfidation methods developed for mZVI are mixing with sulfur-containing reagents [11] or ball milling (wet) in inert gas [12], [13], [14]. The product of ball-milling with elemental sulfur (S-ZVI bm) are superior to reacting with Na 2 S (S-ZVI Na 2 S) in Cr(VI) removal, with both having lower electron selectivity (14.6 % and 13.3 %) [15].

The cost-effective conversion of Hg to HgS is the key to mercury sulfurized stabilization. Fortunately, it has been proved that ball milling of liquid mercury and sulfur can be completely converted into HgS in a short time at room temperature [20], [22], [23]. Such ball milling process is the famous MC method.
