Lead Zinc Separation by Flotation - Froth Flotation (Sulphide
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.

Froth flotation - Wikipedia
The development of froth flotation has improved the recovery of valuable minerals, such as copper - and lead -bearing minerals. Along with mechanized mining, it has allowed the economic recovery of valuable metals from much lower grade ore than previously.

Froth Floatation Process - iCBSE
Froth Floatation Process In some cases for example, sulphides ores of copper, zinc and lead concentration is brought by this method. In this method advantage is taken of the referential wetting of the ore by an oil.The finely ground ore is taken in a tank containing water and 1% of pine oil or terpentine oil .

Froth Flotation Process - Mineral Processing amp; Metallurgy
The process of froth flotation usually involves a series of steps: the preparation of appropriate particle sizes of liberated components in the mixture of solids to be separated; the creation of conditions favourable for the adherence of one or more components in the mixture of solids to attach to air bubbles; and.

How to improve Lead Pb Recovery - Froth Flotation (Sulphide
Floating (collecting froth) for a longer time should increase the recovery. If the froth looks very weak (bubbles breaking easily) then you may want to add one or two more drops of frother to help make the froth stable. Also you said the slimes in flotation are stopping the lead being recovered.

Flotation Froth - an overview | ScienceDirect Topics
Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.

Flotation Depressants - Mineral Processing amp; Metallurgy
First lets change the amount of the Flotation Depressants used. The valuable mineral that isnt liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted minerals color.
