2. 1. Flotation of silicate minerals : physico-chemical studies in the presence of alkylamines and mixed (cationic/anionic/non-ionic) collectors

   Author : Vidyadhar Ari; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

   Abstract : The mechanism of adsorption of long chain alkyl primary amines and, co-adsorption of amines and alcohols on silicate minerals (quartz and feldspar) were studied using FTIR (DRIFT and IRRAS) and XPS spectroscopy methods. The spectroscopy data were correlated with zeta-potential and Hallimond flotation results. READ MORE
