The Yaojialing Zn-Au‑Cu deposit is a porphyry-skarn-epithermal vein-type compound deposit that consists of epithermal vein-type lead‑zinc‑silver orebodies, skarn Zn-Cu-Au orebodies, and porphyry Cu Au orebodies from shallow level to depth. We decipher the source and metallogenic mechanism by studying the trace element and S …

In this research sphalerite flotation from a low-grade lead-zinc ore containing 3% Zn and 1% Pb was studied. Three control parameters including activator (CuSO 4) dosage, collector (potassium amyl xanthate (PAX)) dosage and pH, each in five levels, were investigated.Response surface methodology (RSM) was implemented for …

Creative process, low operation cost. Cu-Pb mixed concentrate regrinding process saves the grinding cost without finely grinding all raw ore, and it makes further monomer dissociation to create favorable conditions for the separation of copper and lead.

cleaner flotation, copper concentrate is produced. Lead concentrates are also obtained from several steps of washing of copper rougher's tails. Ultimately, from washing of copper–lead rougher's tails, the zinc concen-trate is produced [5]. The prevailing process in the Cu–Pb– Zn ores processing on industrial scale is copper–lead ...

They include for example Cu-Zn-Pb, Cu-Mo, Cu-Ni, Cu-Pb ore etc. Figure 1 shows an example of the most common porphyry copper ore type beneficiation flowsheet. Porphyry ores, although generally ...

The low-Cu ore could be processed via the current RPZC flowsheet, but rougher concentrate re-grinds were required.. The high-Cu ore could not be processed via the current RPZC flowsheet to produce distinct Cu, Pb and Zn concentrates.. A feasible flowsheet was developed based on a modified Black Mountain (Cu-Pb-Zn concentrator) …

According to the characteristics of the ore, the innovative process of flash copper flotation in weak acidic pulp and lead flotation, followed by further copper …

Altai orogenic belt is an important Cu-Pb-Zn-Au-Fe polymetallic province in northwest China, with plenty of VMS deposits and ore resources (Fig. 1 a), which is an ideal place and natural laboratory for studying VMS deposits (Windley et al., 2002, Xiao et al., 2004, Yang et al., 2018b).The Ashele Cu-Zn deposit is the largest and most typical VMS …

The Dongshengmiao deposit in the Langshan district is a large Zn-Pb-Cu deposit with reserves of 4.83 Mt Zn at an average grade of 2.85 % Zn, 0.96 Mt Pb at 0.67 % Pb, and 0.11 Mt Cu at 0.86 % Cu (Long, 2009).As the third largest Pb-Zn deposit in China, its genesis has been actively debated since its discovery (Wang et al., 2014).Two …

However, it is unclear whether the conventional approach for Cu-Zn and Cu-Zn-Pb ores (i.e., depression of sphalerite using zinc sulfate) is effective in Cu/Zn separation in the processing of the copper ores excavated …

This observation is true because ore metals such as Pb, Zn, Fe and Cu in sediment-hosted Zn-Pb deposits are commonly derived from the same source, and transported and deposited by the same hydrothermal fluid (Tosdal et al., 1999, Potra and Moyers, 2017) due to their similar geochemical behaviors (Henley et al., 1984).
