Study on Flotation Separation of Galena, Sphalerite with Pyrrhotite in Ethanoic Acid + Sodium Acetate System

摘要：

Flotation separation of galena, sphalerite with pyrrhotite in ethanoic acid + sodium acetate system was studied in this paper. The flotation tests show that galena and sphalerite can float but pyrrhotite can hardly float in the pH range of 3.6 to 5.6 in ethanoic acid + sodium acetate system. The flotation tests also show that galena can be separated efficiently from pyrrhotite and sphalerite can be separated on the whole from pyrrhotite, but the separation efficiency of the former is much better than the latter. The flotation results have been investigated by ultraviolet spectrum and XPS analysis,and explained by theory of hard and soft acid and base (HSAB), hydrogen bond and galvanic coupling.
