Float Metals One-by-One Selectively: Since our objective is to sequentially float Copper, then Lead, than Zinc while rejecting Pyrite, let us explore how we can separate Cu/Pb/Zn from Fe: pH 6-6.5 is where …
A pre-enrichment process of sulfides is therefore deemed necessary for the formation of orogenic base metal deposits, such as the Bainaimiao Cu-Au-Mo deposit, the Huogeqi Cu-Pb-Zn and the Jiashengpan Zn-Pb deposits in the Langshan-Zhaertaishan metallogenic belt (Li et al., 2021, Zhong and Li, 2016, Zhong et al., 2015c, Zhong et al., …
The Dajing Cu–Sn–Ag–Pb–Zn ore deposit, Inner Mongolia of China, is a fissure-filling hydrothermal ore deposit that occurs within the Upper Permian Linxi group.
The prevailing process in the Cu–Pb–Zn ores processing on industrial scale is copper–lead bulk flotation with depression of zinc and then zinc flotation from tails. …
According to the production process of copper concentrate, there are two ways that can reduce Pb and Zn contents in the concentrates: first, depress liberated lead and zinc minerals from the raw ore; second, float lead or zinc minerals from the copper concentrate. Based on these two ways, flotation tests were carried out. Copper flotation.
Ore precipitation in porphyry copper systems is generally characterized by metal zoning (Cu–Mo to Zn–Pb–Ag), which is suggested to be variably related to solubility decreases during fluid...
The Pulang super-large porphyry Cu polymetallic deposit, located in the Sanjiang area of Yunnan Province, is one of the largest Cu deposits in China. This deposit hosts Cu resources of ~5 × 106 t and other ore-forming elements, such as Mo, Au, Ag, Pb, Zn, Pt and Pd. Recently, obvious hydrothermal vein-type Pb–Zn mineralization, with a …
In the flotation of copper - lead - zinc polymetallic sulfide ores, flotation separations of those valuable minerals have been a difficult problem due to their finely-associated intergrowth and similar flotability of these sulfide minerals. ...
