Cu(II) and Ni(II) activation in the flotation of quartz ...

2005-4-4  As was the case with quartz, the maximum change in zeta potential occurs at pH values larger than 6. The effect of xanthate on the zeta potential of lizardite or chlorite is much more pronounced in the presence of Cu(II) than Ni(II) in agreement with the much larger flotation of these minerals obtained with Cu(II) than with Ni(II) .
