The primary objectives of this project are:  to establish the                   applicability of 27Al and 29Si NMR to provide concrete structural               information about the metal hydroxy silicate hydrosol species:  to              provide gel filtration chromatography (GFC) evidence for the polymeric          nature of these species and to use GFC to isolate discrete species:  to         correlate their pH stability range and species composition from NMR and         GFC studies with Ferron and Molybdsilicate assays:  to define the               mechanism of dispersant absorption to various minerals                          usingelectrokinetic, turbidimetric, and solid state NMR techniques, and         to quantify the flotation of copper minerals with a range of Si/Al              dispersants usingmicroflotation techniques.  The dispersant properties          will be quantified with natural copper ores.
