On the other hand, some inadvertent activations are harmful to the flotation separation. It is well known that some divalent ions, like Zn2+, Pb2+ and Ni2+, may accidentally activate quartz, leading to a low-quality concentrate product [7]. The effects of metal ions on flotations have been intensively reported since the 1950s [8].
