Chromium removal and recovery from aqueous media which containing various concentration of (CrO42-)-O-V by hydrothermal mineralization treatment were investigated. Hydrothermal mineralizations with CaCl3 or iron acetate as mineralizer enable effective removal of Cr from aqueous media and it could obtain CaCrO4 or (Fe0.6Cr0.4)(2)O-3 with very high concentration. Cr concentrations in the treated-water by both treatments were independent of the initial concentration of Cr. Additionally, the treatment using iron acetate could obtain Fe-Cr-O type natural mineral ((Fe0.6Cr0.4)(2)O-3) which can be easily reused by industrial resource production system in existence. Thus, the hydrothermal mineralization treatment was one of the effective treatments for Cr removal from wastewater. (C) 2009 The Ceramic Society of Japan. All rights reserved.
