The effect of an external magnetic field on cationic flotation of quartz from magnetite / Mustafa Birinci in Minerals engineering, Vol. 23 N° 10 (Septembre 2010) 

Public ISBD [article]  in Minerals engineering > Vol. 23 N° 10 (Septembre 2010) . - pp. 813–818 Titre : The effect of an external magnetic field on cationic flotation of quartz from magnetite Type de document : texte imprimé Auteurs : Mustafa Birinci, Auteur ; Jan D. Miller, Auteur ; Musa Sarıkaya, Auteur Année de publication : 2011 Article en page(s) : pp. 813–818 Note générale : Génie Minier Langues : Anglais (eng) Mots-clés : External  magnetic  field  Magnetic  flotation  Quartz  Magnetite Résumé : In this study, the effect of an external magnetic field on cationic flotation of quartz from magnetite was investigated by using a magnetic micro-flotation column. For this purpose, a micro-flotation column jacketed with three coils was fabricated to create a funnel-shaped magnetic field. Both the theoretical magnetic field strengths and the magnetic forces were calculated. The results from flotation experiments with 6 × 10−5 M dodecylamine as collector using a binary mixture of quartz and magnetite as a feed material show that the separation efficiency increased from 0% without the magnetic field to 88% in the presence of the magnetic field. The significant enhancement in separation efficiency is evident.
