Extraction of Pb, Cu, Zn and As from Fine Dust of Copper
Fine dust from copper smelting plants is an important source of raw materials for the extraction of various valuable metals. A specific feature of dust from copper smelting plants in Kazakhstan is their high arsenic content of up to 15%. This work shows the possibility of hydrometallurgical processing of fine dust from copper smelters, obtained during the …

Screening and Evaluation of the Bioremediation Potential of Cu/Zn
As expected, the presence of bacteria resulted in increased concentrations of water-extractable Cu, Zn, Pb, Cd, and Fe in autoclaved soil compared to axenic soil (Figure 2). These results suggest that the 10 Cu/Zn-resistant isolates had metal-solubilizing potential in heavy metal-polluted soil, thereby increasing metal bioavailability.
