processes involvled in the mining of chromium

Mining sediments are excavated from nickel ore exploitation in New Caledonia. In those sediments, chromium (Cr) occurs as Cr(III), but Cr(III) can be oxidized to the toxic Cr(VI) under oxic conditions, for instance in overlying water. Here, we aimed to determine whether mining sediments could release available Cr(VI) in surface waters.
