plant dry matter is 3000 mg kg−1; for Co, Cu, and Cr, 300 mg kg−1; for As, Ni, and Pb, 1000 mg kg and dolomite are main minerals in the ore. There are several Zn and Pb mining sites, mostly exploited as open mines; some have been reopened during the last 60 years. In some areas, the s urface soils naturally contain a high background concentration of Pb, Zn, and Ag. Owing to mining
There is an increasing concern on heavy metal leaching from the soils amended with sewage sludge. A column study was conducted to examine the extent of leaching of five important heavy metals (Cd, Ni, Pb, Cu and Zn) from an acidic sandy soil amended with different dolomite phosphate rock (DPR) fertilizers (an application rate of 1% fertilizers) developed from DPR and NViro (consisting of
Plants and the associated soil samples were collected and analyzed for total metal concentrations. While total soil Pb, Cu, and Zn concentrations varied from 90 to 4100, 20 to 990, and 195 to 2200mg kg(1), those in the plants ranged from to 1183, to 460, and 17 to 598mg kg(1), respectively. None of the plants were suitable for phytoextraction because no hyperaccumulator was

21 (PTTE), Cu, Zn, Cr, and As, were investigated in these soils four years after the incorporation of compost 22 (OM, 5% w/w) and dolomite limestone (DL, % w/w), singly and in combination (OMDL), and the 23 transplantation of mycorrhizal poplar and willows. Topsoil samples were collected in all field plots and potted in 24 the laboratory. Total PTTE concentrations were determined in
Dolomite contents in Cutailings were higher than pyrite, but this was the opposite in ZnPb tailings (unpublished data from tailings distribution box, provided by Xstrata Copper Australia). At MIM, the tailings were sampled from the TSFs of different age: TSF (namely MIMTD5, about 40 years after decommission) and TSF (MIMTD7, still active and receiving mixed streams of fresh
Dolomite mining process is the solution of separating dolomite concentrate from Dolomite raw ore. Based on mosaic structure of the Dolomite mine and years of mining process experiences, Xinhai applying Dolomite mining process of twostage crushing, washing, then threestage separating, flotation process will be used to process Dolomite with complex structures.

Concentrations of Cu in the litter leachate were correlated with dissolved organic C (DOC), whereas Zn and Pb were mainly related to leachate pH. Metal concentrations in the soil solution were weakly influenced by their total content in soils and the monthly fluctuations reached 300, 600, and 700% for Cu, Pb, and Zn, respectively. Metal concentrations in soil solutions (Cu 110–460 μg L

The results indicated that the coupled treatment reduced metal concentrations by % Cu, % Cd, and % Pb, while Zn increased due to the natural concentrations of the plant used. This study presents the results of a coupled electrocoagulationphytoremediation treatment for the reduction of copper, cadmium, lead, and zinc, present in aqueous solution.
· Sorption isotherm assays for Cr, Pb, Cd, Zn and Cu, with either single or mixed solutions, were performed using the batch equilibrium technique. The experiments were conducted by adding 20 mL of each metal solution or an equimolar solution of the five metals to 2 g of soil in 50 mL polypropylene centrifuge tubes. The experiments were performed using seven different solutions, prepared on a
In a field experiment we investigated the efficiency of two hyperaccumulating species, four agricultural crop plants, and one woody crop, at phytoextraction of Zn, Cd, and Cu from a polluted calcareous soil. In addition, we examined the possibility to enhance the phytoextraction of these metals by application of nitrilotriacetate (NTA) and elemental sulfur (S8) to the soil.
