Resumen

An experimental study was conducted of the precipitate flotation of calcium sulfite, calcium carbonate, and of mixtures of both particulate species from suspensions of the order 0.1 M, with application to particle separation from the purge stream from a SO2-limestone wet scrubber. The strongly acidic, anionic surfactant, sodium dodecylbenzenesulfonate (NaDBS) provided excellent flotation of both calcium sulfite and calcium carbonate at neutral pH. For concentrations of calcium sulfite plus calcium carbonate of 3.7, 7.8, and 12.0 x 10-2 M, 95% flotation of precipitated sulfite and 97% flotation of carbonate can be accomplished at molar surfactant to sulfite plus carbonate ratios of 0.0035, 0.0023, and 0.0015, respectively.
