flotation process of zinc copper and silver ore

Copper-Zinc Separation. Differential flotation process, floats copper and depresses zinc. If the separating difficulty is over 2, the depression on zinc should be strengthened. Collectors: Low-level xanthate, advanced xanthate, aerofloat. Separation in alkaline medium. Inhibitor: CN-、NaCN、kCN、ZnSO4、Na2OS3、Na2S2O3

copper lead zincores

The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage. In this case, as a general rule because both copper and lead minerals tend to float well, these are usually the target bulk flotation minerals

In the process of flotation, pay attention to the impact of slime on the flotation effect. The flotation of oxidized lead - zinc ore needs to choose suitable reagent and reasonable proportion. Case. According to the design project of a lead-zinc ore concentrator in Tibet undertaken by Xinhai mining equipment, the lead grade of oxidized ore is about 5% and that of zinc is about 15%. In addition, it also contains 80.4g/t of silver …

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 iron sulphide depression

Valuable minerals in an ore can be separated from each other, and from worthless gangue minerals, by the froth flotation process. This process was developed in Australia at the start of the 20 th century to treat the primary sulfidic silver/lead/zinc ore at Broken Hill, NSW. Some of the laboratory observations upon which the process depends were made during the nineteenth century in England, Germany, and …
