The variation in δ 65 Cu AE647 (δ 65 Cu max-min) was larger than that of δ 66 Zn IRMM3702 (i.e., δ 66 Zn max-min), and the isotope values of Zn and Pb (206 Pb/ 207 Pb) tended to increase with the concentrations of these elements. Meanwhile, the fine RDS particles (< 63 µm) had similar Cu, Zn, and Pb isotopic compositions to those of TSS.
Copper ore is mined in Zambia and is typically processed using different types of crushers to extract and refine the copper. The specific types of crushers used …

Historical Pb–Zn mining and smelting in Kabwe in Zambia have made it one of the most polluted cities in the world. Four soil profiles were collected around the smelter and in remote locations, and two pine trees (Pinus montezumae L.) were sampled for tree ring cores.These were analyzed for Pb, Zn and Cu contents and Pb isotopic ratio.
In this study, we present new field geology, whole-rock geochemical and S–Pb isotope data for the Chambishi deposit in the Zambia Copperbelt (ZCB), in order …
The order of contamination by heavy metals on the tailings was Cu > Co > Ba > Ni > As > Zn > Pb > Cr > V > Cd, and that on the overburdens was Cu > Co > Ba > Ni > Zn > Cr > Pb > V > As > Cd. The pollution load index (PLI) was nearly twice higher for the tailings dam (8.97) than the overburden (5.84).

The aim of the present study was to evaluate the spatial distribution of heavy metals in main areas of Zambia and understand the characteristics of the pollution in each area. River and lake sediments and soil samples were collected from a large area of Zambia and analyzed for ten heavy metals (Cr, Co, Ni, Cu, Zn, As, Cd, Pb, Sr and Hg).

The Southern Permian basin in central Europe contains a number of important high-grade sediment-hosted Cu deposits. Laterally extensive stratabound Cu and Zn-Pb sulfide mineralized rocks are located at a major stratigraphic redox boundary, where coarse-grained continental sandstones of the uppermost Rotliegend Group are overlain …
Based on geochemical and fluid inclusion data obtained on different carbonate generations, the Khusib Springs deposit is believed to be of the Cu-rich 'Tsumeb-type' (Verran, 1996, Chetty et al., 1997, Chetty and Frimmel, 2000), which, among other features, is distinguished from the 'Berg Aukas-type' deposits (Cu-poor Pb–Zn deposits …

The results show that, in the sludge sample, the sum of the percentages of the reducible and oxidizable fractions for all metals except Cu was very high (65.4% for Cd, 85.7% for Pb, 78.7% for Zn), whereas the sum of the percentages of the oxidizable and residual fractions for Cu was very high (88.8%).
The Republic of Zambia is an African country that is rich in mineral resources such as copper (Cu), cobalt (Co), zinc (Zn) and lead (Pb) (Stockwell et al., 2001). Mining is the most important industry in Zambia. In 1997, 3% of the world's annual Cu production and 20% of the annual Co production were mined in Zambia and most of

I conducted rougher Cu-Pb-Zn flotation tests and would like to calculate the recovery of the target metal in each circuit (example: Cu in Cu-circuit) as well as the % wrongful recovery of the other 2 metals (Pb and Zn in Cu-circuit). During testing I recorded the masses of the feed, 3 concentrates, and tailings.
The pairs of Cu–Zn (0.486) and Zn–Pb (0.423) showed high and significant correlations at 99 and 95 % confidence levels, respectively. Furthermore, the linear correlation for soil to leaf transfer showed that between Cd in soil and leaf, there is a high and significant correlation (0.560) at 99 % confidence level.
