In decades, various studies on passive treatment methods of acid mine drainage (AMD) have been actively conducted in order to reduce the cost of AMD treatment. Open limestone channel is one of the most common methods and has already been implemented

A passive treatment process using sulfate-reducing bacteria (SRB) is known to be effective in removing heavy metals from acid mine drainage (AMD), though there has been little discussion of the mechanism involved to date. In this work, a sulfate-redu

We treated three samples of wastewater from an abandoned mine using NO3-type Mg–Al layered double hydroxides with different Mg/Al ratios (denoted LDH-2 and LDH-4) and the conventional neutralizer Ca(OH)2. We determined the optimal condition for eac

The effect of controlling the redox potential (Eh) on chalcopyrite bioleaching kinetics was studied as a new aspect of redox control during chalcopyrite bioleaching, and its mechanism was investigated by employing the “normalized” solution redox

In the last two decades, China has struggled with a lot of heavy metal pollution problems, which are mainly caused by the period of high economic growth. Therefore, effective preliminary measures, including low cost treatment techniques should be est

The extremely acidophilic, Fe(III)-reducing heterotrophic bacterium Acidocella aromatica strain PFBC was tested for its potential utility in bioreduction of highly toxic heavy metal, hexavalent chromium, Cr(VI). During its aerobic growth on fructose
Iron redox transformations by five representative Sulfolobus strains (S. metallicus Kra23, S. tokodaii 7, S. acidocaldarius 98-3, S. solfataricus P1, S. shibatae B12) were studied to clarify the general trend of Fe metabolism across different species

The copper refinery process produces Se(VI)-bearing wastewater with a high content of Cl and SO4 ions. To overcome the negative effect caused by Cl and SO4 ions on Se(VI) reduction and its following removal, this study investigated the possible syner
