The chemical forms of heavy metals (Pb, Zn and Cu) in sediment cores of the Pearl River Estuary were studied using a sequential chemical extraction method. The isotope ratios of 206Pb/207Pb in various chemical fractions were also measured to assess the potential Pb sources. Zinc and Cu were mainly associated with the residual fraction.
Abstract. Sulfur and chlorine are the two most important ligands accounting for metal transport in the upper crust. In this study, four metal- and sulfur-saturated model fluids with varying salinities and redox states were simulated in the Fe-Cu-Pb-Zn-Au-S-C-H-O system, over a wide pressure-temperature (P-T) range (50–650 °C, 0.8–5.0 kbar ...
Values of Zn/Pb range from about 100-240 and Cu/ Pb from 100-156. In this study, Zn is found to correlate positively with TiO2 + FeO (mean square of weighted deviates, MSWD, of 1.6 for JFR basalt), and inversely with Mg number (MSWD of 3.5). Therefore, contrary to statements in the literature that Zn should be compatible in MORB, Zn is a mildly ...
This Insight provides an example of one use case for the GHG emissions data delivered by CRU models. Copper concentrate quality drivers. CRU data shows that the average copper concentrate grade has declined by 7% since 2007 (from ~27% to ~25% Cu content). The grade of the concentrate is primarily driven by the mineralogy of the copper deposit ...

Tailings collected from the tailing reservoir at Huogeqi Copper Mine, located in Inner Mongolia, China, were used in a leachate study to evaluate the acid potential, neutralization potential, and possibility for producing acid mine drainage (AMD) from the site. The speciation of Cu, Pb, and Zn contained in the tailings was also determined during the leachate study to further access the ...

The 2022 copper TC/RC benchmark has reportedly been settled at $65/6.5¢ between Freeport McMoRan and Chinese smelters on 16 December. We understand that Jiangxi Copper first agreed at this level with Freeport, with other Chinese smelters following suit (China Copper, Jinchuan and Tongling Nonferrous). This result is consistent with CRU's ...

Copper and Ag are soluble in moderately concentrated chloride brines at intermediate oxidation states, but published data suggest that Cu is strongly adsorbed on goethite and hematite at pH near 7 and temperatures of 0 degrees to 100 degrees C. Also, Pb, Zn, Co, and Ni are soluble in chloride brines, but are only present in some red-bed Cu ...
Solutions of Zn 2+ + Mg 2+ + Ca 2+ + NaCl reacted with S and calcite (sample R11-1) to produce sphalerite and anhydrite as well as Mg-calcite crystals with partial dissolution of the calcite. The Mg-calcite and sphalerite crystals grew in a shell around the dissolving calcite crystal (Figs. 1D and 1E).Sphalerite clusters and galena also grew on the anhydrite crystals when Pb …
