Galena - Sphalerite Flotation & Separation Method

Several processes have been developed for the separation of lead from zinc sulphides by two-stage selective flotation, but the only method that is employed widely enough to warrant a description in these pages is the one whereby the zinc minerals are depressed by sodium cyanide and/or zinc sulphate, allowing the galena, which remains unaffected ...

In single mineral flotation, serpentine depressed the −150 + 74 μm and −74 + 37 μm galena while the −10 μm galena was floatable. Different from galena, serpentine has strong depression effect on all the three sizes of pyrite. So the flotation separation of fine grained galena and pyrite can be achieved.

However, given the unique geological structure of China, sphalerite is commonly associated with metallic sulphide ores, such as chalcopyrite, galena, marmatite, pyrite, and pyrrhotite, which makes it difficult to differentiate sphalerite efficiently [1, 2]. Usually, copper sulphate is used in zinc flotation as an appropriate activator.

Galena Mining Conference - Mining History Association

By 1820, lead mines were operating in several locations. The early discoveries were residual float material in fields and stream gullies. Cerrusite (lead carbonate) and galena (lead sulfide) had been left behind over time as the dolomite and limestone had weathered to form soil.

Effect of surface oxidation on the flotation separation of ...

This study investigated the influence of mineral oxidation on Cu-Pb separation using green reagent sodium humate as depressant for galena. The flotation tests showed that sodium humate had a poor selectivity when it was used alone, especially with high dosage of sodium humate chalcopyrite could be depressed as well.

Flotation process : Sulfur makes up a substantial portion of the mineral in the lead ore galena which is called lead sulfide. The flotation process helps in bringing out the sulfur-bearing portions of the ore, since it also contains the valuable metal. The finely crushed ore is …

How to improve Lead Pb Recovery - Froth Flotation ...

What do you suggest for improving the recovery in flotation of Lead in Lead & Zinc (10% vs. 25%) ore types that consist a high amount of Lead lower than 30um. Basically this ore consist of Fe minerals that rarely influence in flotation procedure. The main problem is the flotation of leads with

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Yunnan lead processing project has complex lead ore to deal with. The main lead minerals are galena and lead alum. It applies the flotation sulphide ore – desilting – flotation oxidation ore processing technology according to the characteristic of lead ores. The final recovery rate of lead concentrate is …

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.

Lead-Zinc ores

Because silver typically is mineralogically associated with galena, most of the silver values are carried with and report to the galena concentrate. Sphalerite that is rejected into the lead flotation tails is then floated in a second flotation step after activation with copper sulphate.

Fundamental Flotation Behaviors of Chalcopyrite and Galena ...

Copper and lead are two important and widely used metals in industry. Chalcopyrite (CuFeS2) is associated with galena (PbS) in ore, and it has been a research hotspot in separating galena from chalcopyrite by flotation. In this study, the flotation behaviors of chalcopyrite and galena were studied through flotation tests, adsorption measurements, solution chemistry calculation, Fourier ...

Lead-Bismuth Flotation - Mineral Processing & Metallurgy

The bulk copper concentrate has no only chalcopyrite, also lead as galena and bismuth minerals such as cosalite, bismuthinite, aikinite, and wittichenite. The idea is separate lead and bismuth minerals from chalcopyrite by flotation. Thus, the copper concentrate will not have penalties for bismuth.
