allows recoveries higher than 85% of Cu and Zn up to frac-
tions of 600µm.
CPF pilot test works demonstrated adequate metallur-
gical scalability. Metallurgical results (recovery and grade)
on pilot scale test works were like the results obtained in
laboratory scale. This finding is well aligned with what has
been reported by other authors.
LCTs conducted with the recirculation of the CPF
concentrate demonstrated the feasibility of cleaning a
HydroFloat polymetallic concentrate. These results showed
that recirculating a reground HydroFloat concentrate at
an optimal PSD (P80 100µm in this case) and under the
appropriate chemical conditions, does not affect either the
recovery or the grade of the Cu and Zn final concentrates.
