“…However, in contrast with our study, Bai used an organic substrate as the main e-donor source. Furthermore, the excellent treatment effectiveness obtained in the limestone columns are in agreement with several studies that demonstrate effective removal of heavy metals by using limestone channels via adsorption or precipitation [41, 42]. …”

This study assessed the bioremediation of acid rock drainage (ARD) in flow-through columns testing zero-valent iron (ZVI) for the first time as the sole exogenous electron donor to drive sulfate-reducing bacteria in permeable reactive barriers. Columns containing ZVI, limestone or a mixture of both materials were inoculated with an anaerobic mixed culture and fed a synthetic ARD containing sulfuric acid and heavy metals (initially copper, and later also cadmium and lead). ZVI significantly enhanced sulfate reduction and the heavy metals were extensively removed (> 99.7%). Solid-phase analyses showed that heavy metals were precipitated with biogenic sulfide in the columns packed with ZVI. Excess sulfide was sequestered by iron, preventing the discharge of dissolved sulfide. In the absence of ZVI, heavy metals were also significantly removed (> 99.8%) due to precipitation with hydroxide and carbonate ions released from the limestone. Vertical-profiles of heavy metals in the columns packing, at the end of the experiment, demonstrated that the ZVI columns still had excess capacity to remove heavy metals, while the capacity of the limestone control column was approaching saturation. The ZVI provided conditions that enhanced sulfate reduction and generated alkalinity. Collectively, the results demonstrate an innovative passive ARD remediation using ZVI as sole electron-donor.

“…HMs discharged into water bodies. Industries such as mining (Alcolea et al, 2012;Davies et al, 2011), tanneries, metal plating, fertilizer industries, battery and pesticide production, ore refineries and the paper industry (Chuah et al, 2005) are the major contributing sources of heavy metal. HMs, such as zinc (Zn), lead (Pb), copper (Cu), iron (Fe), nickel (Ni), and cadmium (Cd) are toxic, carcinogenic, persistent in nature and tend to bioaccumulate (Wan Ngah and Hanafiah, 2008), which has led to the formulation of strict regulations (such as WHO, USEPA or EU) concerning the quality of wastewaters discharged from the industries.…”

Coal/metals, mining, ore processing, and smelting activities pollute water resources with heavy metals all over the world. In this paper, mine waste materials (sandstone) obtained from mine site was used for the uptake of Lead (Pb) ions from the synthetic solution. Laboratory analysis was conceded to study the effects of adsorption parameter like, pH, temperature, contact time, adsorbents dose, on Lead adsorption; the obtained experimental data showed that adsorption of waste materials had a higher adsorption capacity at shorter contact time at pH 5.0. The present investigation demonstrates the sandstone as mine waste material can be effectively utilized for the treatment of Lead (II) laden synthetic solutions by adsorption process.
