摘要：

The present work deals with the flotation behaviour of a mixture of scheelite and calcite. A number of amines, as collector and depressants, were tested. It was observed that the pH of the pulp was important. Flotation combined with washing and/or cleaning operations, was carried out on this mixture. Concentrates containing 63.59-65.51 % WO3 with 96.54-91.41 % recoveries were obtained by using Amine D Acetate as collector from a feed containing 5.93 % WO3. The reason for the high selectivity of flotation combined with washing and/or cleaning was investigated with infrared spectrophotometry and adsorption-desorption tests.
