Stabilization of lead and Zinc Flotation Circuits

Figure 9: Zinc Concentrate Contaminants Versus Time The main reason for this was the lack of adequate lead cleaning capacity, which resulted in a fine balance being drawn between minimizing zinc loss to lead concentrates and recovery of lead from the circuit upstream of the zinc circuit. Iron levels in the zinc concentrate remain at traditional levels despite the significant increase in iron entering the plant.
