Ion flotation using a common cationic surfactant (dodecylamine) a collector was used for the quantative recovery of molybdenum from dilute aqueous solutions.When arsenic co-existed with molybdenum in the solution, both arsenic and molybdenum were recovered. In this case, adsorbing colloid flotation, using ferric hydroxide as co-precipitant (or sorbent) and also dodecylamine as collector, has been examined for the selective separation of arsenate from molybdate anions. It was found that over 98% of arsenic could be separated from the molybdate solution at pH 9, while the loss of molybdenum in the foam (in one stage) was less than 10%. the flotation mecanism by dodecylamine is discussed and also compared with that of sodium dodecyl-sulphate, a common anionic surfactant.
