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., …
A Cu-Pb-Zn sulfide ore from Somincor (Neves Corvo, Portugal) with a chemical composition of 0.5% Cu, 1.2% Pb, 7% Zn, 32% Fe and 43% S was used. The ore sample is a massive sulfide ore containing chalcopyrite, galena, sphalerite and pyrite as the major sulfide minerals.

Jinchanghe is a Zn-Pb-Fe-Cu skarn deposit in the northern Baoshan block, southwestern China. It is a typical distal skarn deposit with orebodies in the Cambrian Hetaoping Formation limestone and calcareous siltstone. The skarn minerals display a vertical zonation with garnet skarn in the lower part and pyroxene skarn in the upper …
order of flotability from high to low. In a beneficiation tests of a Cu-Pb-Zn polymetallic sulfide ore, the sequential preferential flotation process by the order of copper- lead-zinc was adopted[2], and the products, including copper concentrate assaying 19.84 % Cu at recovery of 60.25 %, lead concentrate
From the standpoint of evaluating the potential of mineral resources, we construct a Pb-Zn deposit predictive type of classification scheme, and propose a Pb-Zn deposit comprehensive classification scheme (including 5 classes and 13 sub-types) that regards mineralization as the primary factor and the ore rock as secondary.
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.
The flowsheet in this study was designed to treat 500 tons per day of a complex base metal ore containing gold and silver values. The presence of free gold offers opportunity to recover these values in the grinding circuit so that the gold could be amalgamated, and marketed directly to the mint. The ore as ... Process …
