Abstract. flotation is a process used worldwide to separate metallic and nonmetallic minerals from extracted ore. It is probably the single most important operation used in the mining industry in the world today. In the United States, for example, over one-third of the mineral concentrates produced are obtained using flotation [I].

Introduction. Froth flotation is a widely applied method to improve the quality and reduces impurity of concentrates depending on the significant difference in their surface physical and chemical properties [1], [2].During flotation, it is expected that a kind of mineral adheres to air bubbles and floats upward into the froth layer, and other …

It is evident that the reverse flotation provided a satisfactory separation performance as in the case of direct flotation using oleate as collector. These flotation results are in line with the expectations from the contact angle measurement (Fig. 2, Fig. 3) and single mineral flotation tests. It should be noted that in the reverse flotation ...
