Zinc also occurs in ... In flotation, workers use slurry reagents to float the heavy mineral away from the lighter powdered ore. Slurry ...
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 type collectors. Because most of the iron sulphides also report to the lead flotation tails and so feeds the zinc flotation circuit, typically lime is used to raise pH for ...
Pb–Zn–Cu complex ore from Balıkesir–İvrindi district have been concentrated by GESOM A.Ş. using a selective mechanical flotation technique. Ore feeds containing 3.23% Pb, 0.52% Cu, and 2.71% Zn were concentrated by six stages of cleaning and four stages of scavenging. The final zinc ...

Furthermore, in order to float the zinc minerals remaining in the tailings, same type of collectors such as dithiophosphate and amines were used after activation with copper sulfate, but there was no possibility for flotation of zinc minerals.
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.

Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed by froth flotation. Without froth flotation, many of the metals and minerals used every day in our modern world would be much more expensive.
The Qixia orebody is a complex lead–zinc sulfide system with pyrite gangue and minor amounts of copper. In order to improve the flotation results, laboratory scale flotation testing of ore samples taken from this operation was performed.
The bulk copper–lead flotation with depression of zinc followed by copper–lead separation and re-flotation of zinc is the most common practice in the treatment of copper–lead–zinc ores. About 90% of operating plants use this method. The bulk concentrate is usually contaminated with pyrite and zinc.
Some plants find it beneficial to use a visual sampler on the lead tailing ahead of the zinc circuit. The Sampler is also useful for evaluating the lead or zinc concentrate. General view of the flotation section at a modern silver-lead-zinc mill. The lead circuit is on the left and the zinc circuit is on the right.

Zinc Sulphide Ore Wholesale, Sulphide Ores Suppliers. froth flotation for oxide copper and lead offers 20 zinc sulphide ore products. About 55% of these are mineral separator, 15% are general reagents, and 10% are other mining machines.
To improve the selectivity between copper and lead, a sequential copper-lead-zinc rougher circuit was tested. Each of the rougher circuits had a dedicated regrind and cleaner circuit. The advantages of the sequential circuits are that the levels of selectivity can be increased, particularly for copper and lead.
