Sequential Copper–Lead–Zinc Flotation

2015-1-8  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.

1996-11-1  The optimurn conditions under which the flotation recovery of copper, lead and zinc is highest are found in these cases. Electrolytic flotation experiments under the same conditions as by dispersed-air flotation lead to an almost 100% removal, since a large amount of very small bubbles is formed, resulting in a greater surface area (with minimum turbulence) during electroly- sis.

DE-ZINCING OF LEAD-COPPER SULPHIDE MINERALS

Typical lead-copper-zinc sulphide minerals were found hard to be separated selectively by froth flotation in the plant practice operation due to part of sphalerite was progressively entrapped into lead-copper bulk flotation. A series of de-zincing on lead-copper flotation tests has been conducted in the laboratory to reduce unwanted zinc content.
