Abstract

The influences of Al3+ from recycled water of mineral processing on molybdenite floatability and its mechanism of action were systematically studied, through flotation tests of molybdenite, measurement of electric potential, Al3+ solution chemical analysis, and X-ray photoelectron spectroscopy (XPS). The results indicated that Al3+ can worsen the flotation index of the molybdenite and lead to a significant deviation of its surface potential, indicating that there is lots of Al3+ adsorption on the surface of molybdenite. Al3+ in solution mainly exists in the forms of aluminum ion, hydroxy aluminum ion and aluminum hydroxide. Hydroxy aluminium ion, aluminum hydroxide precipitation with a strong polarity, can adsorb on lively “edge” of molybdenite, and the aluminum ions can produce chemical reaction with MoO42? because of molybdenite “edge” oxide generated. With the reason of the area of “edge” much smaller than that of “face”, the aluminum ions are mainly adsorbed on the “edge”, so the content of aluminum is not much, but the aluminum ions can adsorb on the surface of molybdenite, indeed both physical adsorption and chemical adsorption.
