It was found that zinc ion could be removed from aqueous solutions by adsorbing colloid flotation with Fe(OH){sub 3} and sodium lauryl sulfate (SLS) provided that the ionic strength of the solution is low (containing no greater than 0.02 M NaNO{sub 3}). An excess dose of iron resulted in poor separation. Three types of polyelectrolytes were used as the activators to compensate for the effect of increasing ionic strength of the solutions. Betz 1150 (a weakly cationic acrylamide copolymer) was found to be the most effective activator. The separation was effective from a solution containing NaNO{sub 3} as high as 0.7 M when Betz 1150 was used as the activator.
