The bulk concentrate is subsequently conditioned with sodium hydroxide to achieve an approximate 11.5 pH and collector addition from which a lead concentrate is floated. The zinc concentrate is actually the tails from this bulk separation step. The flotation tailing is the zinc concentrate.

If lead, zinc and copper are sulphides, the logical process is to produce a Pb-Cu bulk concentrate, and tails from the Pb-Cu flotation circuit feed the zinc flotation circuit. In this case, the lead content is much higher than copper content, then it would be necessary to depress lead and float copper.

Mar 01, 2016· Based on the placement of lead and its consumption in industry branches, the paper deals with the composition of lead in the massive of Kopaonik. Removal, tenuity and grinding of galenit. The paper in particular treats the flotation process. Also treats physico-chemical bases of reagents in the process, as well as decanting, drying, filtering and storage of concentrates.

• Lead concentrate is the result of a flotation process after the ore has been mined and milled. • Lead concentrate is an intermediate product used as raw material in the production of lead metal. Above Products analysis regarding various minerals of mines can be changed

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.

Lead Concentrate - sormakmine.com. Sormak Mining Co. which produces 4000 ton lead concentrate annually is one of the most important suppliers of lead concentrate for Iranian Lead and Zinc National Co. In addition, in a near future, after running a hi-tech flotation cells the results shown below will improve significantly.

The Jameson Cell is a high-intensity froth flotation cell that was invented by Laureate Professor Graeme Jameson of the University of Newcastle (Australia) and developed in conjunction with Mount Isa Mines Limited ("MIM", a subsidiary of MIM Holdings Limited and now part of …

Flotation of Aladag oxide lead-zinc ores. ... As a result of gravity concentration followed by flotation, a lead concentrate with an average Pb content of 65.80% was produced with 86.5% total Pb ...

Utilization of polysaccharides as depressants for the flotation separation of copper/lead concentrate Article (PDF Available) in International Journal of Mining Science and Technology 23(2):179 ...

Sormak Mining Co. which produces 4000 ton lead concentrate annually is one of the most important suppliers of lead concentrate for Iranian Lead and Zinc National Co. In addition, in a near future, after running a hi-tech flotation cells the results shown below will improve significantly. Two distinct types of lead concentrate are producing in our factory.

It is necessary to recover as much silver as possible in the lead concentrate as a higher return for this silver is realized than for the silver in the zinc concentrate. The ore contained sphalerite, a portion of which was easily floatable but difficult to depress in the lead flotation circuit.

Aug 07, 2019· Lead concentrate grades ranged between 67.9% to 72.1% Pb Flotation Test Work Details Froth flotation tests were performed with various XRT material sorter concentrates from the …

The final molybdenum concentrate is typically greater than 55%. Lead/Zinc Ore. Lead and zinc often occur in the same ore. Copper is also present in some ores. Froth flotation is again employed to produce marketable concentrates of both. The process is identical in principle to the flotation of other minerals.

Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also ... flotation to produce concentrates of 50 to 60 percent zinc. Lead ore also requires processing to ... Smelting is the process by which rough lead bullion is produced from lead concentrate. After the

• Lead concentrate Processing Costs - LPC, • Zinc concentrate Processing Costs - ZPC. Criteria above are applied to formulate MCDM problem. Pb-Zn concentrate A finely ground ore Pb-Zn flotation circuit Bulk tail Pb concentrate Pb flotation circuit Zn flotation circuit Zn concentrate Bulk tail A finely ground ore Pb-Zn concentrate Pb-Zn

Utilization of polysaccharides as depressants for the flotation separation of copper/lead concentrate. ... the separation of bulk copper/lead concentrate is common used in commercial process and forms the backbone of this investigation. ... Flowsheet of bulk copper/lead flotation-reagent removal-separating flotation. 2.3. FTIR studies.

The ways to obtain successful Separation of Copper and Lead into individual Concentrates, several process approaches can be examined; bulk copper-lead flotation with a reverse flotation stage depressing copper, the same bulk flotation with a reverse flotation to depress lead and a sequential copper-lead-zinc flotation circuit as well as a simple cleaning of the bulk Cu/Pb concentrate by Pb ...

The rougher concentrate is normally subjected to further stages of flotation to reject more of the undesirable minerals that also reported to the froth, in a process known as cleaning. The product of cleaning is known as the cleaner concentrate or the final concentrate.

On-stream analyzers, providing real-time assay information, control the flotation circuit. The result is a zinc concentrate at 55.2% Zn, 3% Pb and 137g/t Ag and a lead concentrate at 56.1% Pb, 11.7% Zn and 435g/t Ag. The concentrates are dewatered using pressure filters.

A wide variety of lead ore concentrate options are available to you, such as gravity separator, flotation separator. There are 394 lead ore concentrate suppliers, mainly located in Asia. The top supplying countries or regions are China, South Africa, and Nigeria, which supply 77%, 2%, and 2% of lead ore concentrate respectively.


The sulphidized lead minerals are subjected to flotation using xanthates or mercaptans and pine oil to produce a flotation concentrate which is cleaned two times to produce a high grade marketable lead concentrate. The flotation tailing from the lead section passes to a wet cyclone to make a primary sand-slime separation.

obtaining a lead concentrate with low content of arsenic. Ore sample, which was used in this flotation testing, contained a large amount of arsenopyrite (over 40% by mass). The results showed that arsenic content in the rough lead concentrate can be decreased up to ten times compared to its content in the ore, using NaCN as depressant.

The lead ore concentrate from the flotation tanks now contains about 50% lead and ca 0.1% of silver, a relatively small but valuable amount. (b) Smelting. Smelting is usually a two-stage process as described here, although single-stage methods with lower energy use and emissions are also used.
