Copper Lead Concentrate Separation

A process to produce higher grade copper concentrates by depression of lead. The sequential flotation process produced the best batch test results: The test had the highest selectivity between copper and lead. Copper in the feed was, on average, 63 percent recovered into a copper concentrate grading 24 percent copper and 1.6 percent lead.

08-01-2015  In these tests, a zinc flotation was also performed to measure the metallurgical performance of that metal. The flowsheet schematic and summary of test results. As shown in the summary tables, copper was, on average, 63% recovered into the copper concentrate grading 24% copper. The recovery and grade of unwanted lead and zinc was very low when compared to the other flowsheets. Lead in the feed was, on average, 36% recovered into a concentrate

Therefore the standard Cu-Pb-Zn flotation practice involves an initial flotation of a Cu-Pb bulk concentrate followed by two parallel circuit stages of copper-lead separation and separate zinc flotation from the bulk flotation tails. As described in the lead-zinc ore processing section, zinc sulphate and metabisulphide sphalerite and pyrite depressants, respectively, are typically added to grinding.

separation by flotation of copper lead zinc sulphides

30/03/2020 With respect to the flotation of copper–lead–zinc sulfide ores, copper–lead mixed flotation is the most common method used to obtain a copper–lead concentrate. Therefore, the separation of chalcopyrite and galena from a mixed concentrate is necessary. Depressants are a good choice to prevent galena from floating.

Typical lead-copper-zinc sulphide minerals were found hard to be separated selectively by froth flotation in the plant practice operation due to part of sphalerite was progressively entrapped into lead-copper bulk flotation. A series of de-zincing on lead-copper flotation tests has been conducted in the laboratory to reduce unwanted zinc content.

The concentrate products of copper, lead, and zinc can be obtained via flotation separation. The concentrate products of sulfur can be obtained only when the ore’s pyrite content is high. Gold and silver can be recovered from the concentrates of copper, lead, and zinc or from the products of pyrite. The goal of floating pyrite is not to recover
