“…Discrete Ni-sulfides are rarely observed in nature (see Huang et al, 2010 for a brief review of their occurrences). Nonetheless, Ni-sulfides readily form in experiments employing high concentrations of Ni comparable to those found in polluted streams (Lewis and Swartbooi, 2006;Karbanee et al, 2008;Cao et al, 2009;Sampaio et al, 2010;Reis et al, 2013;Kiran et al, 2015). Additionally, geochemical observations indicate that Ni removal is decoupled from Fe precipitation in sulfidic and weakly acidic (pH 4-6) pore waters, suggesting the formation of discrete Ni-sulfides under these conditions (Huerta-Diaz et al, 1998;Frohne et al, 2011).…”

Biogenic and Abiogenic Fe-Ni-Sulfide Nanoparticles Fe-S phases is primarily determined by the precipitation kinetics, and our experiments at [Ni] aq /[Fe] aq = 1:1 suggest that Ni-sulfide precipitation kinetics is comparable or higher than Fe-sulfides at this condition. Overall, our study allows for prediction on the phases and biogeochemical factors controlling Ni removal and availability in sulfidic environments.

“…Removal of metals as sulfide precipitates to treat AMD and recover valuable metals was studied using either Na 2 S or biogenic sulfide (Reis et al, 2013). At pH 7, the removal efficiency of nickel reached 99.9%, corresponding to a residual level of 0.13 mg/L.…”

Globally, mine drainage is a persistent environmental problem facing the mining industry. This review covers the literature published in 2013 on topics relating to acid mine drainage (AMD) or acid rock drainage (ARD) due to the presence of sulfide bearing minerals in active and abandoned coal/hard rock mining sites or waste spoil piles. This review is divided into the four sections: 1) mine drainage characterization, 2) mine drainage treatment 3) modeling and simulation, and 4) environmental aspect. Mine Drainage Characterization Physicochemical Characterization. The characteristics of mine sites have profound impacts on the quality and quantity of acid mine drainage (AMD) or acid rock drainage (ARD), the toxicity of the contaminants, the fate and transport of the metals, and the required treatment or remediation methods. The mine drainage from the Globe-Progress gold mine, New Zealand, were circumneutral (pH 6-8) with high HCO 3 -and SO 4 2-(both up to 300 mg/L) and elevated As (0.5 mg/L) and Sb(~3 mg/L) (Druzbicka and Craw, 2013). The Sb/As ratio in the mine drainage ranged from 1 in historic mines, to ~30 below the modern mine. It was found mining methods and contrasting ore types had a dramatic effect on the metalloid contents. The characteristics of alkaline mine drainage from 11 active and abandoned mines were examined in the Lokpaukwu-Ishiagu mining areas of Nigeria, where very high concentrations of TDS, hardness, chloride, calcium,

“…The adsorption of Ni(II) from aqueous solution on laponite as a function of contact time, pH, ionic strength, laponite dosage, and temperature was studied via batch technique. Different methods, such as chemical precipitation [2], ion exchange [3], membrane separation [4], electrocoagulation [5,6] have been used to remove heavy metal ions from aqueous solutions. Adsorption of Ni(II) on laponite is strongly dependent on pH but independent on ionic strength.…”

“…Therefore, decreasing Ni(II) concentration before discharge to the environment is important to protect environmental and human health. Different methods, such as chemical precipitation [2], ion exchange [3], membrane separation [4], electrocoagulation [5,6] have been used to remove heavy metal ions from aqueous solutions. However, most of these techniques have some disadvantages such as complicated treatment process, high cost, and energy use.…”

Silicate‐bearing hectorites (laponite) were synthesized by hydrothermal method, and the laponite sample was characterized by Fourier transform infrared (FTIR) spectroscopy, X‐ray diffraction (XRD), zeta potential, Brunauer‐Emmett‐Teller (BET) surface area, and pore size analyses. The adsorption of Ni(II) from aqueous solution on laponite as a function of contact time, pH, ionic strength, laponite dosage, and temperature was studied via batch technique. The maximum removal of 99% (approx) could be achieved at the optimum adsorbent dosage of 2.5 g L−1 and near‐neutral pH. Adsorption of Ni(II) on laponite is strongly dependent on pH but independent on ionic strength. At low pH, the adsorption of Ni(II) was dominated by ion exchange with Li+ on laponite surfaces, whereas inner‐sphere surface complexation and surface precipitation were the main adsorption mechanisms at near‐neutral pH and alkaline environment, respectively. The adsorption kinetic data of Ni(II) on laponite were well described by the pseudo‐second‐order kinetics model. The intraparticle diffusion was involved in the adsorption process but was not the only rate‐controlling step. The adsorption isotherms of Ni(II) on laponite can be described well by the Langmuir model and the maximum Ni(II) adsorption capacity of laponite obtained from Langmuir model was 65.79 mg g−1. The thermodynamic studies indicated that the adsorption of Ni(II) on laponite was endothermic and spontaneous. The laponite exhibited excellent adsorption properties for Ni(II) uptake compared with various adsorbents, indicating that it is a suitable material as an adsorbent for preconcentration and immobilization of Ni(II) from aqueous solution. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 942–950, 2018
