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-Lead-Zinc ores - danafloat.com
Copper-Lead-Zinc ores. The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage. In this case, as a general rule because both copper and lead minerals tend to float well, these are usually the target bulk flotation …
Flotation of Copper-Lead-Zinc Ores - ResearchGate
In the flotation of copper–zinc massive sulfide ores, the flotation properties of copper and zinc are determined by the nature and composition of the ore. Selectivity between chalcopyrite and...
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.

Bulk flotation vs. Selective flotation - Froth Flotation ...
For Copper and Lead flotation: We need to float both minerals 1st. We call it Bulk flotation. Then this bulk concentrate will go to Cleaning stage where we depress Copper, and float Lead-This process we call selective flotation. Case study-2. For Zinc and Lead Flotation. Here we depress Zinc and float Lead-This is called selective flotation. Case study-3

Separation may be a simple bulk float (i.e.pyritic gold ores, some copper ore with negligible pyrite) or as is the case for polymetallic ores, a complex three stage sequential separation (ie copper, lead, zinc).
Lead-Zinc ores - Danafloat
Sphalerite that is rejected into the lead flotation tails is then floated in a second flotation step after activation with copper sulphate. The copper ions replace zinc atoms on the sphalerite surface creating a pseudocopper mineral surface coverage on the sphalerite which is then collected using copper flotation type collectors.

It is reported that more than 90% of non-ferrous metal ores (copper, lead, zinc, etc.) adopt flotation process, especially for those with fine stone and complex symbiosis. Flotation process can achieve ideal separation effect, and separately recover low-grade ore then enrich multiple high-grade concentrates.

As an example of metals that often occur together in ores can be specified copper, lead, zinc, silver and gold, where lead (Pb) and zinc (Zn) can particularly be highlighted as metals whose minerals usually occur together in ores. To further processing these minerals, it is usually necessary to make their separation, where the froth flotation is commonly used in for beneficiation of valuable minerals.
