Heavy metal (Pb, Zn, Cd, Fe, and Cu) contents of plant

In addition to Pb and Zn, the primary ore constituents, copper (Cu), iron (Fe), and cadmium (Cd), were also assayed. As expected, foliar Pb and Zn concentrations were elevated in plants at the sites closest to the mill, i.e., 0.25 and 2.5 km from the mine facility.

Gold Smelting Refining Process

Gold Smelting Equipment It has been shown that concentrates obtained by gravity devices and cathodes can be smelted directly most the time. Silvergold concentrates can be smelted too. Under this consideration, a concentrate must contain at least 20 oz/t of gold. Obviously, if the higher grades are better and 50 oz/t is a good average value.

Distribution of Cd, Pb, Zn and Cu and their SpringerLink

In general, Cd, Zn, Pb, Cu and As presented a significant contamination in the area near the smelter, comparied with Environmental Quality Standards for Soils in China. The geoaccumulation index showed the degree of contamination: Cd > Zn > Pb > Cu > As. There was no obvious pollution of Cr and Ni in the studied area.
