For example, in the flotation of lead-zinc sulfide ore, it is necessary to separate lead, zinc and sulfur. At this time, flotation reagents are used to change the nature of one of the minerals and separate them one by one. In the case of lead-zinc separation, the "zinc-inhibited and .
Used as the collector for the flotation of non-ferrous metal mineral which need strong collector but no selectivity. It is a good collector for the flotation of oxidized sulfide ore or copper oxide and zinc oxide (vulcanized by the sulfiding agent）as well as copper-nickel sulfide ores and gold bearing pyrite ores .
Silver Lead Zinc Ore Processing Method using Flotation. Also the recovery of silver minerals occurring in a lead zinc sulfide ore is efficiently accomplished using Flowsheet #2. The process consists of selective flotation to produce a mixed silver lead concentrate for maximum smelter return and a separate zinc concentrate.
The flotation of mixed lead-zinc ore can be carried out in lead sulfide → lead oxide → zinc sulfide → zinc oxide → lead sulfide → Zinc sulfide → lead oxide. Jaw Crusher, Cone Crusher : crush ore to a smaller size, make the target minerals and gangue minerals dissociated.
Aug 05, 2020· For example, when impurities such as ZnS is present in galena (PbS), sodium cyanide (NaCN) is added to depresses the flotation property of ZnS by forming a layer of zinc complex Na2[Zn(CN)4] on ...
The lead-zinc sulfide is often associated with a variety of valuable components, such as lead, zinc, copper, sulfur and other useful minerals, whose floatability is obviously different, which determines the different froth flotation process of lead and zinc sulfide ores. The common froth flotation process of sulfide ore mainly includes priority ...
Table of ContentsChemistry of Sodium SulfideSulfidization Sodium Sulfide in Sulfide Minerals Flotation Sodium sulfide is one of the most widely used alkali metal sulfides in the flotation of copper, lead, and zinc minerals in their oxidized form. The sulfidization process, developed in the U.S.A. in 1915-20 for oxide copper minerals flotation, is especially suitable for oxidized lead ores in ...
Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture. The flotation is made selective by using reagents, which make the Cu-sulfide minerals water-repellant (hydrophobic) while leaving the other minerals wetted (hydrophilic).
It is an effective collector for copper, lead and silver sulfide ore and activated zinc sulfide ore. It is commonly used in the priority flotation separation of lead ore and zinc ore. In the alkaline medium, the dithiophosphate 25 has weak collecting effect to pyrite and other sulfide .

The lead-zinc sulfide is often associated with a variety of valuable components, such as lead, zinc, copper, sulfur and other useful minerals, whose floatability is obviously different, which determines the different froth flotation process of lead and zinc sulfide ores. The common froth flotation process of sulfide ore mainly includes priority ...
Flotation experiment research on a polymetallic sulfide ore of. 2016-10-04 The polymetallic sulfide ore of copper, lead, and zinc is widely found all over the world and is often associated with rare metals such as gold and silver.
Base metals such as copper, lead, and zinc are mainly extracted from sulfide ores. Mostly these base metals tend to exist together in an ore. Flotation process is widely used to separate these minerals in sulfide ores . A wide range of chemical reagents are used in the flotation process to separate the different minerals.
The invention relates to a method for pretreating ore pulp in a lead and zinc oxide flotation process. In the method, after a pH regulator, an inhibitor and a collector are added in turn before the rough concentration of lead and zinc oxides, stirring and pulp regulating are performed respectively, pulp regulating is also performed before the concentration of rough concentrate and before the ...
The flotation response of a Pb Zn sulphide ore from the Rosh Pinah Mine (Namibia) was studied in the presence of inorganic depressants such as sodium cyanide and zinc sulphate. Poor flotation selectivity was observed in the rougher concentrate of the galena circuit despite the use of

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.
5 Flotation Processes Used to the Extraction of . Here is the introduction of five flotation processes used to the extraction of lead-zinc sulfide ores.. In nature, the lead-zinc minerals mainly include lead-zinc sulfide and lead-zinc oxide ore. The lead-zinc sulfide accounts for a large proportion and has the higher industrial application value.
This paper reports the results of flotation tests conducted with a copper-lead-zinc sulphide ore. The major sulphide minerals in the ore are chalcopyrite, galena, sphalerite, marmatite and pyrite ...
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.
Aug 01, 2009· This investigation was performed with samples from a lead–zinc sulphide deposit aiming at studying the influence of the dispersion degree of the particles in the pulp on lead and zinc flotation. Samples of ore and also of the minerals sphalerite, galena, pyrite, .
