Abstract
The effects of pH, ionic strength, and specific ions on the adsorbing colloid flotation of lead(II) and zinc(II) with AI(OH)3 and Fe(OH)3 with sodium lauryl sulfate (NLS) as collector are reported. Floc foam flotation of lead with Fe(OH)3 and gelatin, with MnO2 and NLS, and with CaCO3 and NLS or hexadecyltrimethylammonium bromide was studied. Lead is efficiently removed with Fe(OH)3 and NLS; zinc with Al(OH)3 and NLS. A theoretical study was made of the effect of the charges of ions present as inert electrolyte; separations decrease in efficiency with increasing charge at constant ionic strength.Keywords
