En general, la mayor dificultad de la separación de minerales de sulfuro polimetálico es la separación entre varios tipos de minerales, especialmente aquellos de baja ley con características incrustadas complejas. Por lo tanto, es un paso significativo que ...
The particle size of tailings was in the range of 10-100 microm. The pH of the waste covered a wide range, from 1.73 to 8.11, and was influenced by associated minerals and elevated levels of Cd, Cu, Pb, and Zn, extracted by a Korean Standard Method (digestion with 0.1 mol L(-1) HCl), which were found in the wastes.
Thermodynamic description of the ternary Cu–Pb–Zn system is presented. The adjustable parameters of the sub-systems, Cu–Pb, Cu–Zn and Pb–Zn, are taken from earlier SGTE-based assessments and those of the ternary system are optimized in this work using the experimental zinc activity and phase equilibrium data.

The K d values obtained by Engates & Shipley (2011) in their study of the sorption of metals (Pb, Cu, Cd, Zn, and Ni) onto nano-TiO 2 from tap water were one to five orders of magnitude higher than obtained in the present study. This was expected because much higher competition for sorption sites occurs in ion-rich marine water.

The results show that the maximum simultaneous adsorption of metals equilibrated with 10 mg/L mixed Cd, Cu, Pb and Zn solution; and ≥ 90% Cd and Pb and over 70% Cu and Zn absorbed by ~ 1.0 g PRH at room temperature but typically the sorption efficiency dropped off past 20 mg/L concentration, which is likely due to saturation of sorption sites.

While distributions of Pb and Cu were similar, total concentration trended to decrease from 0 to 10 cm and increase at a depth of 10–20 cm, perhaps because Cd and Zn are more mobile than Pb and Cu. In smelter soil, the mineral content was high with low redox potential, and heavy metals will cause potential harm to the deep soil along with the ...

An attempt was made from separate published data to correlate total soluble Cu, Zn, Cd and Pb in soils to soil pH, organic matter content and total metal content. For Cu, the total Cu content of the soil was most highly correlated with total soluble Cu. Similarly, total soluble Zn and Cd were correlated with total metal content, but were more ...

First, the cell voltage was controlled at zero, which allowed recovery of Cu from the solution without an electrical energy input. Second, the cathode potential was controlled at -0.51 V to recover Pb, which required an applied voltage of about 0.34 V. Third, the cathode potential was controlled at -0.66 V to recover Cd, which required an ...
The chemical associations of Cd, Cu, Pb, and Zn in four mine soil samples from the Amizour-Bejaia Pb/Zn mine (Algeria) have been investigated by a five-step sequential extraction procedure. Although Cd preferentially binds to carbonates, Cu, Pb, and Zn are mainly associated with the organic and reducible fractions. Batch adsorption experiments with either …
