The adsorption of dehydroabietylamine acetate on quartz, hematite, rutile and baddeleyite has been determined for concentrations ranging from 0.3 to 5,600 μ. moles/I and for pH values ranging from 2.5 to 10.5. The surface tension, UV and IR spectra, equivalent conductance and ion concentrations for dehydroabietylamine acetate solutions have been determined. Contact-angle and flotability studies have established that good collection may be obtained with this amine but that selectivity depends on the suitable use of depressants for some of the minerals.
