Binary and ternary separations of heavy metals, e.g. Zn–Bi, Mn–Pb, Cd–Pb, Mn–Bi–Mo, and Cr–Pb–Bi on columns of titanium(IV) tungstosilicate and Zn–Ni, Mo–Pb, Hg–Pb, Zn–Cr–Bi, and Zn–Ni–Bi on titanium(IV) tungstophosphate, have been demonstrated. The adsorption and elution of important metal ions such as Mo, Al, and As on titanium(IV) tungstosilicate and Hg, Fe, and Cr on titanium(IV) tungstopho...

soils around mining sites play a significant role in the transport and control of heavy metals in the environment. therefore, understanding the adsorption properties of soil is essential in solving pollution problems. the objective of this paper was to study zn(ii) adsorption onto sarcheshmeh copper mine soils. the adsorption isotherms of zn(ii) were studied. the langmuir isotherm indicated an ...

The growth response, metal tolerance and phytoaccumulation properties of water spinach (Ipomoea aquatica) and okra (Abelmoschus esculentus) were assessed under different contaminated spiked metals: control, 50 mg Pb/kg soil, 50 mg Zn/kg soil and 50 mg Cu/kg soil. The availability of Pb, Zn and Cu metals in both soil and plants were detected using flame atomic absorption spectrometry. The concen...

this study aimed to explore concentration of a low grade sulfide-oxide lead-zinc sample containing 2.3% pb, 1.91% zn taken from changarzeh mine, south natanz, iran. the effects of different parameters such as type and dosage of collector, milling retention time, dosage of sodium sulfur and its preparation time, application of sodium silicate, ph and solid content were investigated in relation t...

a well-known algorithm of clustering is k-means by which the data are divided into k classes based upon a distance criterion. in the present research, by using k-means method for classifying data derived from exploration boreholes in the parkam deposit, the optimum k has been calculated and then the data have been clustered and the relative geochemical behavioral characteristics analyzed. the c...

The potential environmental impact of historical mining and ore processing on stream sediments water was studied in a small siderite iron deposit with diverse sulfide mineral paragenesis. main aim to characterize solid carriers potentially toxic elements (PTEs) mine waste, understand their fate fluvial systems. General mineralogy (X-ray powder diffraction) individual PTE (scanning electron micr...

China holds large-scale lead–zinc mineral resources; however, mining activities often cause severe contamination by heavy metals. This study systemically assessed eight metals (Cu, Zn, Cd, Pb, Cr, Hg, Ni, and As) in mine tailings, soil, groundwater from 27 contaminated sites across China. Regarding 1% of the tailing samples were hazardous waste 20% class II non-hazardous waste. Zn Pb showed hig...

The Bainiuchang Ag polymetallic deposit is located at the junction between Cathaysia, Yangtze, China and Indosinian blocks. It has experienced many geological events, records excellent conditions for multiple mineralization. In this paper, elemental correlation analysis, cluster factor a semivariogram of Zn/Pb values, mineralization distribution trend surface analysis have been carried out base...

Through field investigation and experimental analysis, the forms, contents distribution of heavy metals (Zn, Pb, Cu, Cd, Ni, Cr) in rhizosphere non-rhizosphere soils Miscanthus floridulus growing everywhere Tielongwei mine pond (sample plot 1), Caoduikeng tailings 2), Donghua 3) Small 4) Dabaoshan, Guangdong Province were studied. The results showed that main forms distributions are basically s...

In this study, concentrations of Cr, Mn, Pb, Cu, Zn, As, Cd, Sb, and Fe were determined in soils a Pb-Zn mine watershed northern Guangxi, China, for ecological risk assessment source analysis. The atomic fluorescence spectrometry ICP-OES used to determine heavy metals (HMs), the total amount Pb exceeded limit. Among them, weak acid extractable fraction (F1) state masses Zn accounted higher risk...
