The adsorption determinations of Sodium Oleate (NaOL) and Dodecylamine (DDA) on scheelite mineral (Ca WO4) were performed by a spectrophotometric method. Study of collector concentration (ranging from 1 to 1000 mg L-1) vs pH (ranging from 2 to 12) is presented. The results are represented in the different graphs. They allow for comparison with the scheelite flotation results. The latter were carried out by the vacuum method. The mineral preparation methodology was the same used in vacuum flotation experiments.
