Selective and direct sorption of zirconium from acidic leach liquor of zircon concentrate by rice bran / Ehsan Zolfonoun in Minerals engineering, Vol. 23 N° 9 (Août 2010)  

Public ISBD [article]  inMinerals engineering > Vol. 23 N° 9 (Août 2010) . - pp. 755–756 Titre : Selective and direct sorption of zirconium from acidic leach liquor of zircon concentrate by rice bran Type de document : texte imprimé Auteurs : Ehsan Zolfonoun, Auteur ; Akbar Boveiri Monji, Auteur ; Mohammad Taghizadeh, Auteur Année de publication : 2011 Article en page(s) : pp. 755–756 Note générale : Génie Minier Langues : Anglais (eng) Mots-clés : Zirconium Zircon concentrate Biosorption Rice bran Résumé : A new method for extraction of zirconium from leach liquor of zircon concentrate is proposed. The procedure is based on the adsorption of Zr(IV) ions on rice bran. The sorption capacity of the biomass for zirconium is 50 mg g−1. Adsorption equilibrium was achieved in less than 1 min and slightly affected by solution acidity. In the optimum conditions, the adsorption efficiencies of other associated metal ions such as Ti4+, Fe3+, Al3+, La3+, Ce3+ were significantly lower than Zr(IV) ion and this biomass is excellent sorbent for the selective uptake of zirconium from acidic aqueous solutions.
