Bioaccumulation of As, Cd, Cr, Cu, Pb, Zn in . in the polluted area by enterprise for the production and processing of batteries. Ambrosia artemisiifolia L, . .) in
As, Cd, Cr, Cu, Pb, Zn was highlighted in different parts of the plant. According to plant-up taking indexes studied elements can be ranked in the following descending order: Cu>Zn>Cr>Cd>Pb. Ambrosia artemisiifolia L. could be proposed for phytoremediation in Zn, Cu, Cd, Cr contaminated soils although this species is resistant for lead soil
At a milling speed of 500 rpm, and BPR 12, the leaching concentrations of Pb, Cu and Zn decreased with increasing milling time as shown in Fig. 2.The leaching concentrations of Pb, Cu and Zn in untreated soil were 13.92 mg·L −1, 2.71 mg·L −1, and 114.31 mg·L −1, which were 273 times, 2.6 times, and 113 times higher than the Class …
In the course of the research, the leaching efficiency of metals including Fe, Sn, Mn, Al, Cu, Zn, Pb, Ni, Ti, Sb, Cr, Co and V was evaluated depending on process parameters, such as AC density ...
The scientific aim was to evaluate the feasibility of rhamnolipid-mediated phytoextraction of heavy metal ions from soil located in the vicinity of a copper smelter, taking into account four major aspects: i) selectivity of rhamnolipids towards Cu, Zn, Pb, Cd and Fe during soil washing; ii) phytoextraction efficiency of each ion with respect to ...

By comparing Table 4 with Table 1, the Cu recovery was not changed significantly from 83%, while the Pb and Zn recoveries in copper concentrate decreased significantly from 83.49% and 79.69 to 66.48% and 58.49%, respectively, and the total content of lead and zinc decreased from 13% to less than 11%, which created favorable …
Part of large-scale industrial test results of milling fineness influence on lead, copper and zinc minerals flotation results in the Rudnik flotation plant are shown in this paper. Based on industrial research it has been concluded that one-stage milling and two-stage classification of complex Pb-Zn-Cu ore leads to so-called "differential …
Creative process, low operation cost. Cu-Pb mixed concentrate regrinding process saves the grinding cost without finely grinding all raw ore, and it makes further monomer dissociation to create favorable conditions for the separation of copper and lead.
4.5 L Denver flotation cell was used and the same flotation conditions were applied in all of the tests: Cu-Pb Flotation: 500 g/t MBS to ball mill, grind size p80 = 60 µm, 10 min pre-aeration (pH 6.5–7), 30 g/t Aero3418A as collector (stage addition was applied), 25 g/t MIBC as frother, 6 min of total flotation time..

About Pb-Cu. Lead and zinc are extremely close in nature, especially in primary deposits, and often coexist. Most of the lead-zinc minerals are sulfides and sulfates, and galena and sphalerite are the primary Pb-Zn ores. Non-sulfide: It is formed due to hypogene and supergene weathering. Mostly oxide ores like zincite, and cerussite may fall under this …
