Sequential Copper–Lead–Zinc Flotation


To improve the selectivity between copper and lead, a sequential copper-lead-zinc rougher circuit was tested. Each of the rougher circuits had a dedicated regrind and cleaner circuit. The advantages of the sequential circuits are that the levels of selectivity can be increased, particularly for copper and lead. With this process, copper was recovered first with MBS depression of lead, zinc and ...
