Orogenic-type deposit is one of the most important economic deposit types in the world and accounts for large amounts of metal reserves, especially gold, in the world (Goldfarb et al., 2005, Chen, 2006, Fan et al., 2022).The orogenic-type deposit is typically hosted in shear zone and the ore-fluid associated with the orogenic …
HM include essential metals (Cu, Zn, Co, Cr, Mn, and Fe), non-essential metals (Ba, Al, Li, and Zr), less toxic metals (Sn and As), and highly toxic metals (Hg, Cd, and Pb) (Duffus, 2002). When the rate of intake of these HM by biological systems exceeds the rate of excretion, then we call that bioaccumulation of HM in biological systems ( …

1.. IntroductionThe accumulation of heavy metals in agricultural soils is of increasing concern because of food safety issues, potential health risks, and its detrimental effects on soil ecosystems (McLaughlin et al., 1999, Cui et al., 2004).Hg, Pb and Cd are of great concern because of their toxicity to human health and other organisms, whereas …

Regarding the relation between Zn and Pb, these authors pose synergistic effects seen in several plants species where increases in Zn uptake are due to Pb presence with increased toxicity related to leaf chlorosis and growth inhibition, among other effects, while Musielińska et al. (2016) indicate antagonists relations between these two …
Float Metals One-by-One Selectively: Since our objective is to sequentially float Copper, then Lead, than Zinc while rejecting Pyrite, let us explore how we can separate Cu/Pb/Zn from Fe: pH 6-6.5 is where Pb/Zn/Fe are least hydrophobic while Cu is most hydrophobic. Great pH to Recover Cu. pH 7.5-8 is where Zn/Fe are least …
At lower concentrations, the ability was slightly higher for Cd, but at higher concentrations, Zn uptake was slightly higher. The order of accumulation of heavy metals in Tagetes erecta L. shoots was in the order of Cd > Zn > Pb, and the same order for roots was Zn > Cd > Pb. The bioconcentration factor (BCF) was greater than 1 for Cd (soil ...
The results also show that Cu, Zn, Cd and Pb can be removed from the fly ash with high efficiency using hydrochloric acid leaching, which is beneficial since these metals are potentially toxic. The nitric acid systems shows less efficient leaching of Cu and Zn as well as poor leaching efficiency of Pb; only 9% could be removed at pH 2.
