The detoxification of water contaminated by antimony and its resource recovery are achieved by hydrothermal mineralization treatment. The treatment is based on the precipitation method of a mineral from aqueous media by imitating natural mineralization mechanism derived from activity of magma. The treatment could reduce Sb concentration in aqueous media, when the formed mineral was Ca-2(Sb2O7), which resembled natural mineral of Monimolite ((Pb,Ca)(2)Sb2O7). The antimony concentration in water after the hydrothermal mineralization under optimal conditions was 0.06 mg/dm(3). Additionally, the rapid cooling of the treated water made much progress in the treatment efficiency to disturb the re-dissolution of the formed mineral. Therefore, this treatment is effective for detoxification of water polluted by antimonic species and its resource recovery.
