Stabilization of lead and Zinc Flotation Circuits

The additional flow sheet modification that increased zinc flotation residence time provided the additional recovery gain up to circa 90% (7% gain in zinc recovery) that had a payback of 6 weeks on capital cost. The optimization of this circuit and the introduction of a lead cleaning circuit will be the subject of a subsequent paper.
