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 …

Effects of particle size on flotation performance in the ...

Therefore, in all the experiments of copper-lead separation flotation and gold-lead separation flotation, the separation efficiency of the intermediate size fractions is the highest. A lower SE value of gold-lead for the coarse size fraction may be due to insufficient liberation of gold from galena or other gangue minerals.

Froth flotation - Wikipedia

The testwork was aimed at improving selectivity in samples of a copper/lead ore from the GECO mine located at Manitouwadge, Ontario. The basic components of the flotation circuit involve the combination of a differential circuit for copper/zinc separation and a bulk/selective circuit for copper/lead separation.

Copper-Lead-Zinc ores - Danafloat

The zinc reporting to the bulk flotation tails feeds the zinc circuit which is operated as previously described in the lead-zinc flotation section. Which flotation scheme used in the differential copper-lead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate.

Utilization of polysaccharides as depressants for the ...

1. Introduction. In the flotation of complex sulfide ores, the two methods most widely used for the separation of economic amounts of copper and lead are presents as the following: (1) bulk copper/lead flotation followed by copper/lead separation; (2) sequential copper/lead flotation .The sequential separation has some disadvantages, for example, large reagent dosage, complex flowsheet, etc.

Can anybody give me some ideas to separate copper and lead?

Lead and copper are routinely separated using two stages of flotation, ie first the copper or lead is recovered to produce a concentrate, then a second stage of flotation to recover the other ...

Introduction to Mineral Processing - Chevron Phillips Chemical

The tailing from the lead flotation circuit is the feed to the zinc circuit. The ability to selectively float the separate minerals depends on the ore, the chemicals, and other factors. Conclusion. Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed by froth flotation. Without froth ...

Research on Separation of Copper-Lead Mixed Concentrate

The ore is the oxide ore of Copper lead and zinc, The ore has high Oxidation rate of Pb,nearly 50%. which contains 3.56% of Pb,3.86% of Zn,0.209% of Cu. The flotation flowsheet consisting of the scene is "Part of the mixed flotation—inhibitor Zn and Pb-Cu mix flotation—Zn flotation—Cu-Pb separation". But the Cu-Pb separation was not effective.

Cu-Pb-Zn, Copper-Lead-Zinc Ores, Copper Lead Zinc ...

In general, the most difficulty of the polymetallic sulfide ores separation is the separation among several kinds of ores, especially those low-graded ores with complex embedded features. Therefore, it's a significant step for separating lead-zinc, copper-zinc, copper-lead to choose right flotation reagents.

Flotation Froth - an overview | ScienceDirect Topics

A concentration of 25–30% is suitable for economical smelting of copper. The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail ...

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 ...

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 extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

DE-ZINCING OF LEAD-COPPER SULPHIDE MINERALS …

the flotation separation is difficult when lead, cop-per and zinc need to justify concentration into three perfect separate products. Flotation problems in general are due to geological origin; hence, the ore have controlling influence on flotation practice. More specifically, the resultant copper or lead ions

Copper-Zinc ores - Danafloat

The flotation separation and recovery approach is quite similar to the Pb-Zn sulphide separation process. Sphalerite is depressed with zinc sulphate addition to the grind with sodium sulphide as an option for enhancing pyrite depression. Copper is floated in the first differential flotation stage at a …

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 from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows the formation of air bubbles.
