Lead Zinc Separation by Flotation Froth Flotation

Some of the metals that can do the job are copper and lead. At a pH between 8-9 lead can activate sphalerite to cause it flotation. So the reason is during the flotation of the two there may be lead re dissolution from galena which may activate sphalerite to cause it flotation. It may best if you are doing bulk flotation of the two.

Copper Lead Separation by Lead Depression

Another method to separate Pb from Cu is in depressing the lead away from the copper to float. Here, three batch cleaner tests were performed with additional depressants to reject more lead from the copper flotation concentrate. The baseline test utilized no MBS depression in the rougher circuit to maximize copper recovery, but MBS depression in the copper cleaner circuit (Test 18).

A Novel Technology for Separating Copper, Lead and Zinc in

The copper–lead–zinc ore found in the Jiama mining area of Tibet has a high mud content, a high degree of oxidation, and complex properties, so it is extremely difficult to separate copper, lead, and zinc using a single flotation technology. Therefore, it is necessary to develop an alternative process to achieve separation of these.

High Efficiency Lead Zinc Flotation Machine Separating

Lead zinc flotation separating process: The flotation-cell is mainly used to select copper, zinc, lead, nickel, gold and other non-ferrous metals. The flotation plant also can be used for the roughing and selection of ferrous metals and metalloid. In the process of flotation separation, the ups and downs of minerals almost have nothing to do

Copper extraction Wikipedia

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

Foams in mineral flotation and separation processes

Ninety percent of the world’s copper, lead, zinc, molybdenum, antimony, and nickel are produced by processes employing concentration of ore by flota tion. Although the processing of mineral ores is by far the largest use of flotation separation, numerous other processes have been developed for the separation of other materials.
