闪锌矿通常是用铜离子活化后再用短链黄药进行浮选的。Fink等曾详尽地研究过这种硫化物的活化、减活和抑制的化学机理,而且证明过这种系统的复杂性。作为一种半导体,纯闪锌矿与方铅矿、黄铜矿和黄铁矿之类矿物不同之处在于它有很宽的带隙(-3.5电子伏特)。所以,从电化学角度上讲,闪锌矿不象它们那样能促使有助于浮选的疏水物质的形成。加入Cu~(2+)离子会因为离子交换反应而在闪锌矿表面上 Sphalerite is usually activated by copper ions followed by short chain xanthate flotation. Fink et al. Have exhaustively studied the chemical mechanisms of activation, deactivation, and inhibition of such sulfides and have demonstrated the complexities of such systems. As a semiconductor, pure sphalerite differs from minerals such as galena, chalcopyrite and pyrite in that it has a very wide bandgap (-3.5 eV). Therefore, from an electrochemical point of view, sphalerites do not, unlike them, promote the formation of hydrophobic substances that contribute to flotation. Addition of Cu 2+ ions will be on the surface of the sphalerite due to the ion exchange reaction
