Synthesis and collecting properties of novel carboxyl hydroxamic acids for diaspore and aluminosilicate minerals / Jiang Yu-ren in Minerals engineering, Vol. 23 N° 10 (Septembre 2010) 

Public ISBD [article]  in Minerals engineering > Vol. 23 N° 10 (Septembre 2010) . - pp. 830–832 Titre : Synthesis and collecting properties of novel carboxyl hydroxamic acids for diaspore and aluminosilicate minerals Type de document : texte imprimé Auteurs : Jiang Yu-ren, Auteur ; Yin Zhi-gang, Auteur ; Yi Yun-lai, Auteur Année de publication : 2011 Article en page(s) : pp. 830–832 Note générale : Génie Minier Langues : Anglais (eng) Mots-clés : Collector  Flotation  behavior  Adsorption  mechanism  Diaspore  Aluminosilicate  mineral Résumé : Novel carboxyl hydroxamic acids compounds, including 2-carboxyl-6-methylcyclohexane carboxamic acid (CMCA), 2-carboxymethyl-decylen-4-yl hydroxamic acid (CDHA), and 2-carboxymethyl-tetradecen-4-yl hydroxamic acid (CTHA) were synthesized, and the flotation behaviors of diaspore, kaolinite and illite were investigated by using these compounds as collectors. The adsorption mechanism of CTHA on the surface of diaspore, kaolinite and illite was conducted by zeta-potential, adsorption amount and FTIR spectra measurement. The interaction of CTHA on the diaspore surface may be mainly dominated by the chemical adsorption; however, the adsorption of CTHA on kaolinite or illite is mainly dominated by the physical one.
