Lead Zinc Separation by Flotation - Froth Flotation ...
Some of the metals that can do the stone 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.
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.
Froth Flotation Method - JXSC Machine
The froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons: (1) In most cases, the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent and discard a large number of tailings, thus reducing the smelting cost.

SURFACE TENSION. Froth Flotation Frothers are chemicals used to strengthen the SURFACE TENSION of an air bubble. They do not create air bubbles. To demonstrate surface tension, fill a glass of water just prior to over flowing, you will notice that the surface of …
1 Froth Flotation – Fundamental Principles
1 Froth Flotation – Fundamental Principles. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.
How to Process Low-Grade Lead Zinc Ore by Flotation
Zinc Flotation. Zinc concentrates are fed to a Wilfley Table to remove any lead oxide values which may have floated with the zinc, and then are thickened in a Thickener. A Adjustable Stroke Diaphragm Pump takes the thickener underflow to a 6′ Disc Filter.
Introduction to Mineral Processing - Chevron Phillips Chemical
Introduction to Mineral Processing. The process of froth flotation entails crushing and grinding the ore to a fine size. This fine grinding separates the individual mineral particles from the waste rock and other mineral particles. The grinding is normally done in water with the resultant slurry called the pulp.

The flotation tailing from the lead section passes to a lifting conditioning tank represent the feed to the zinc flotation section. The combined products flow to a zinc conditioning tank where soda ash, sodium silicate and an organic colloid are added to disperse the pulp and complex the slimes which might interfere with flotation.
What is the gold froth flotation process? - Quora
Froth flotation process is a kind of gold mining process that makes the useful minerals adhere to the bubble for achieving the gold separation with the flotation reagents based on the difference of physical and stone properties of mineral surface. The froth flotation process can be used to deal with the nonferrous ores, such as copper, lead, zinc,sulfur and molybdenum.

Lead-Zinc ores
The established lead-zinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression). Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression.
