The soil at the copper and zinc rolling site exhibits a composite contamination of heavy metals such as Cu, Ni, Zn, Pb, as well as organic compounds such as TPH and PAHs.
As, Cd, Cu, Ni, Sb, Pb, and Zn in digested soil or plant samples were then analyzed in ICP-AES (inductively coupled plasma–atomic emission spectrometry; Ultima2 JY, Horiba Company, Edison, NJ,
There are no formal standards or screening values for TPH values, but the data show significant elevations of TPH in all underpass sediments compared to reference conditions (Figure 3).

Results showed that the spatial distribution of TPH and HMs were similar but opposite in temporal. Ni, Cr, Pb, and Co concentrations were similar to the reference values (RVs). However, the other five HMs (Cu, Zn, Cd, As, and Hg) and TPH concentrations were 2.00–763.44 times higher than RVs; hence, this deserves attention, particularly for Hg.

The 7xxx (Al-Zn-Mg-Cu) alloys were extensively utilised in aerospace and rail transit due to their low density, high strength, and excellent processability. Nevertheless, an increase in strength inevitably comes at the expense of ductility, and vice versa, which was known as the "strength-ductility trade-off" dilemma. Extensive research had been conducted to address this issue ...
However, Cu, Zn, Pb, Cd and Hg exceeded the standard in some samples, and all higher than background values in the study area, which indicated that the soil was contaminated in some parts of the ...
The results of this study reveal that: (1) monthly average dust deposition rates varied from 5.1 in educational areas to 50.6 g/m2 in industrial areas, with average deposition rate of 16 g/m2; (2) the average concentrations for Zn, As, and Pb in the dust samples were up to 8.6, 7.3, and 6.5 times, respectively, higher than soil background ...
For the high-Cu ore, the challenge was to produce three distinct Cu, Pb, and Zn concentrates. Whilst the initial approach of exploiting relative flotation kinetics using the current RPZC operating conditions did not achieve the desired Cu-Pb selectivity, a feasible flowsheet was developed based on a modified Black Mountain (Cu-Pb-Zn
Moreover, the removal efficiencies are 30.2% for Al, 98.79% for Cu, 99.0% for Fe, 17.2% for Mn, 93.4% for Pb, and 62.4% for Zn in actual acid mine drainage using 6 g L-1 adsorbent.
