Solid−Solution Speciation and Phytoavailability of Copper .

The soil solution speciation and solid-phase fractionation of copper (Cu) and zinc (Zn) in 11 typical uncontaminated soils of South Australia were assessed in relation to heavy metal phytoavailability. The soils were analyzed for pH (4.9−8.4), soil organic matter content (3.5 to 23.8 g of C kg-1), total soil solution metal concentrations, Cus (49−358 μg kg-1) and Zns (121−582 μg kg-1 .

Nov 01, 2009 · Zn was the most abundant in all cases presented; Pb was also always enriched compared to Cu (Pb/Cu>1), while Cd was found to be enriched by Legret and Pagotto (1999), but depleted compared to Cu by Davis et al. (2001) and in this study. All values for Zn, Pb, and Cd were noticeably different from the soil ratios, as were this study's ratios .

A high positive correlation was found between Zn, Cu, and Cd (r > 0.8), while Zn, Cd, and Cu (r > 0.7) were positively correlated with total organic carbon. Principal component analysis indicated that Cr, Ni, Mn, and As was mainly from the lithogenic origin and Zn, Cu, Cd, and Pb were influenced by anthropogenic contamination.

I think you should increase the dosage, it seems low. For example, if the head grade reports 1% Pb and 3% Zn, the addition of ZnSO4 could be 700 g/t in grinding, 100 g/t in rougher flotation. In this case, activated sphalerite is not a problem. NaCN should be added in the grinding circuit (e.g. 20-30 g/t).

Impact of Cu(II) and Zn(II) on the Reductive Dissolution .

Dissolved lead (Pb) concentrations in drinking water are mainly controlled by Pb-containing minerals in corrosion scales on lead service lines. Lead(IV) oxide (PbO2) solids can control lead concentrations at very low values, but they are stable only in the presence of a free chlorine residual. When free chlorine is depleted, PbO2 undergoes reductive dissolution. Zinc (Zn) and copper (Cu) may .
