Developing and testing a novel biological reduction cell to remediate heavy metal and acid-containing industrial and mine leachates

点击翻译按钮获取中文摘要

Echo Remediation Ltd. has a new reduction cell that uses sulfur and bacteria to remove heavy metals and acidity from mine leachates, but development is now required to make it viable. The project aims to optimise the process using molecular approaches to study the effects of operating conditions on the bacterial communities. As part of the investigation, active iron reducers will be selected and introduced to the cell (in conjunction with chemical amendments) and their colonization monitored. The new technology once developed has the potential to be used at mine sites in Australia and overseas and its employment offers a sustainable, biological "green" approach to mine waste remediation.
