9-1 TECHNICAL NOTES 9 FLOTATION Flotation is the most widely used mineral separation method It is the preferred method of mineral recovery for many of the most important minerals that are recovered and large tonnages of ore are.

Collectorless Flotation of Sulphide Minerals

mill operators sometimes observe incidental collectorless flotation of minerals such as galena and sphalerite The significance of collector.

Flotation Basics

Froth Floatation Floatation is an extractive process where various minerals can be selectively extracted For example, in poly-metal ores such as Pb-Zn-Cu, floatation allows separate extraction of Pb, Cu and Zn.

Flotation Monitoring and Optimization

Flotation Monitoring and Optimization A particle-by-particle view of operational effectiveness Severe political and economic challenges, as well as increasing costs for production resources, are driving a renewed focus on operational efficiencies in mining and mineral processing.

Froth flotation

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicityHydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.


Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water.

Froth flotation circuit design and basic testwork

Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash.


A flotation method for concentrating iron-bearing oxide ores wherein the ore is both activated by a cation of a heavy metal and conditioned with a collector at a temperature within the range of 80*-100*C and floated at a temperature within the range of 50*-80*C.

The chemistry of the activation of sulphide minerals by Cull) and other cations is reviewed, with special emphasis on work published in the past two decad.

Copper ores

Sulphide flotation of actual oxide copper minerals (such as malachite, azurite) is not possible with sulfhydryl mineral flotation collectors and either other oxide.

Flotation Reagents

Orica offers a broad range of flotation reagents for mineral processing, such as collectors, frothers, activators, modifiers and depressants.


Lecture 5 Flotation 1 CHAPTER 7- FLOTATION OF SULPHIDE MINERALS Contents: Xanthate adsorption Oxidation reactions Activation & depression Flotation of chalcopyrite, galena, sphalerite, pyrite.

Fatty acid flotation versus BHA flotation of tungsten

This study revealed the reason of the low recovery of the traditional flotation process of tungsten minerals The aim of this work is to show the selective adsorption of a new collector, lead complexes of benzohydroxamic acid, and hence improve the selective flotation of tungsten minerals from calcium minerals.

Imhoflot™ Pneumatic Flotation Plants

Imhoflot pneumatic flotation technology has evolved through 25 years of industrial applications This has led to the development of the patented Imhoflot G-Cell where centrifugal forces are used in the cell to quickly separate the phases after mineral collection and therefore considerably reducing the size of vessels required.

A flotation separation method of antimony sulfide gold minerals comprises the steps of performing bulk flotation to obtain antimony-gold mixed concentrate firstly and then separating the antimony-gold mixed concentrate to obtain antimony concentrate and gold concentrate, wherein in the bulk flotation, lead nitrate is taken as an activator for.


Background Froth flotation is the follow-on operation, after comminution and classification, in the process of liberating and separating minerals by exploiting the differences in physical properties of the different minerals that make up an ore.

A Review of the Flotation of Copper Minerals

Copper is most commonly present in the earths crust as copper-iron-sulphide and copper sulphide minerals, for example, chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4) and chalcocite (Cu 2 S).

Single mineral flotation tests are widely used as a reference in flotation separation research to investigate the floatability of minerals for evaluating actual ore.

Depressants and dispersants

In mineral flotation the challenge is to maximize the recovery of desired minerals while rejecting unwanted gangue components Depressants are required to give a low affinity to active sites on valuable mineral surfaces and a high affinity for gangue minerals.

Froth Flotation Process

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them.

Modified column flotation of mineral particles
