INFLUENCE OF PYRITE CONTENT ON THE FLOTATION OF

The flotation experiments for the various blends were repeated several times in order to assess reproducibility of the results. As an example, values of chalcopyrite (Cp) and pyrite (Py) recovery after 10 min of flotation, and the first order flotation rate constant (k) for three tests with 20% pyrite content are summarised in Table 2.
