An ore containing 5% of lead is fed to a bank of flotation cells. High grade concentrate is produced from the first circuit (Circuit 1) assaying 52% of lead while the tailing from this circuit assay 0.7% lead. The tailings feeds a lower grade circuit (Circuit 2) that produce a contrite grading 8% lead and a tailing that contain 0.2% lead. Calculate the weights of high and low grade concentrates and the recovery of lead to concentrates. The feed tonnage to circuit 1 is 28t/h.
