The PI proposes to develop efficient methods of processing iron and             phosphate ores.  The proposed work deals with the interfacial processes         in iron oxide-silica system with the specific purpose of developing             flocculants that can produce selective aggregation of component                 minerals.  Topics such as adsorption of surfactants and polymers on             mineral surfaces, electrokinetic studies under conditions similar to            those encountered in actual seperation processes and possibilities for          selective flocculation seperation between hematite and clays by                 flocculants with functional groups such as hydroxamates will be                 investigated.
