Abstract
Six carbon-containing sorbents prepared from brown coals were used to purify mine water from the Kizelovskii basin. The main physicochemical characteristics and process regimes of the purification of acidic mine water were determined under laboratory conditions. The initial coals and spent carbon-containing sorbents were characterized. It was found that this purification process resulted in a decrease in the total hardness and sulfate content by 15–27% and to the almost complete removal of harmful metal cations from mine water. The results of the analysis of spent carbon-containing sorbents demonstrate that they can be utilized by thermal oxidation.
