HOW TO ASSESS POTENTIAL BIOLOGICAL EFFECTS OF SUBAQUEOUS DISPOSAL OF MINE TAILINGS: LITERATURE REVIEW AND RECOMMENDED TOOLS AND METHODOLOGIES

Mine Environment Neutral Drainage Program, MEND Report 2.19.1, 158 pp, 2018

Subaqueous disposal (SAD) or flooding of sulfide-rich tailings in constructed facilities is a method used at some mine sites to mitigate the formation of acid mine drainage. The primary SAD mitigation mechanism is limitation of oxygen ingress into water-filled pores, which greatly reduces sulfide oxidation, minimizes metal leaching, and prevents acidic drainage development. The overall biological performance of such facilities is not well understood. In particular, a major gap in understanding relates to the biological colonization of such facilities, the health of biological communities that are established, and the influence of those communities on water and sediment geochemistry. This report contains an introduction, an extensive literature review (Sections 2-7), and a set of recommendations on tools and methodologies that might be used to assess the biological effects of submerged tailings. http://mend-nedem.org/mend-report/how-to-assess-potential-biological-effects-of-subaqueous-disposal-of-mine-tailings-literature-review-and-recommended-tools-and-methodologies-2018/
