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

Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture.
