The flotation circuit features silver-lead flotation and zinc flotation circuits. The silver-lead flotation stage will recover a silver-lead concentrate, which will feed the silver-lead regrind circuit comprising a cyclone cluster and stirred horizontal regrind mill. The tailings will be conditioned and then sent to the zinc flotation circuit.

Figure 11 shows the results of two campaigns on a 9-cell rougher flotation line at Los Pelambres Mine, Chile . The line comprises 5 banks in a 1-2-2-2-2 configuration (i.e., 1 single cell followed by 4 pairs of 2 cells). Figure 11a shows Cu cumulative grade down the line and Figure 11b shows the corresponding bank-by-bank Cu recovery profiles.

MINING. The polymetallic ore supplied to the Boliden concentrator in 2005 came from the Maurliden open pit, which started up in 2000, and the three established underground mines. The underground mines are mainly worked by various cut-and-fill techniques, with all activities thoroughly mechanised. Open cuts are worked by contractors.
