Abstract Acid mine drainage (AMD) is the most serious environmental problem facing the Canadian mineral industry today. It results from oxidation of sulphide minerals (e.g. pyrite or pyrrhotite) contained in mine waste or mine tailings and is characterized by acid effluents rich in heavy metals that are released into the environment. A new acid remediation technology is presented, by which metallurgical residues from the aluminium extraction industry are used to construct permeable reactive barriers (PRBs) to treat acid mine effluents. This technology is very promising for treating acid mine effluents in order to decrease their harmful environmental effects

Title Constructed wetlands technology and water quality improvement: Recent advances Type Journal Article
Year 2005 Publication Proceeding of the 9th International Conference on Environmental Science and Technology Vol B – Poster Presentations Abbreviated Journal
Volume Issue Pages B503-B508
Keywords mine water treatment
Abstract Today's demands for improved water quality in receiving waters are widespread and require the implementation of systems that are natural, low-cost and minimal-maintenance that could effectively treat polluted discharges. Wetlands are such systems and are recently receiving a lot of attention from scientists, ecologists and engineers, as they are deemed appropriate for reducing the impact of effluent and run-off on receiving waters. Since a large part of natural wetlands have been lost-about 53% of them in the United States from the 1780s to the 1980s-management options for improving receiving water quality, water reclamation and reuse involve the application of constructed wetlands technology.

Title Agricultural soils irrigated with acidic mine water: Acidity, heavy metals, and crop contamination Type Journal Article
Year 2005 Publication Australian Journal of Soil Research Abbreviated Journal
Volume 43 Issue 7 Pages 819-826
Keywords Contamination and remediation Irrigated agriculture Soil studies geographical abstracts: physical geography soils (71 5 14) international development abstracts: agriculture and rural development (74 1 8) ecological abstracts: terrestrial ecology (73 4 2) bioaccumulation irrigation agricultural soil acid mine drainage pH crop plant heavy metal China Far East Asia Eurasia
Abstract Agricultural soils irrigated with acidic mine water from the Guangdong Dabaoshan Mine, China, were investigated. The pH of the soils could be as low as 3.9. However, most of the mineral acids introduced into the soils by irrigation were transformed to insoluble forms through acid buffering processes and thus temporarily stored in the soils. Different heavy metals exhibited different fraction distribution patterns, with Zn and Cu being mainly associated with organic matter and Pb being primarily bound to oxides (statistically significant at P = 0.05). Although the mean of exchangeable Cd was greatest among the Cd fractions, there was no statistically significant difference between the exchangeable Cd and the oxide-bound Cd (the 2nd greatest fraction) or between the exchangeable Cd and the carbonate-bound Cd (the 3rd greatest fraction). It was also found that there were generally good relationships between the concentrations of various Zn, Cu, Pb, and Cd fractions and pH, suggesting that a major proportion of each heavy metal in the soils was mainly derived from the acidic irrigation water. The results also show that the crops grown in these soils were highly contaminated by heavy metals, particularly Cd. The concentration of Cd in the edible portions of most crops was far in excess of the limits set in China National Standards for Vegetables and Fruits and this can be attributable to the extremely high transfer rate of Cd from the soils to the crops under the cropping system adopted in the study area. < copyright > CSIRO 2005.

Title Biological removal of arsenic from tailings pond water at Canadian mine Type Journal Article
Year 2005 Publication Arsenic Metallurgy Abbreviated Journal
Volume Issue Pages 209-214
Keywords mine water treatment
Abstract Applied Biosciences has developed a biological technology for removal of arsenic, nitrate, selenium, and other metals from mining and industrial waste waters. The ABMet((R)) technology was implemented at a closed gold mine site in Canada for removing arsenic from tailings pond water. The system included six bioreactors that began treating water in the spring of 2004. Design criteria incorporated a maximum flow of 567 L/min (150 gallons per minute) and water temperatures ranging from 10 degrees C to 15 degrees C. Influent arsenic concentrations range from 0.5 mg/L to 1.5 mg/L. The ABMet((R)) technology consistently removes arsenic to below detection limits (0.02 mg/L). Data from the full scale system will be presented, as well as regulatory requirements and site specific challenges.

Title Software Update to Better Predict Costs of Treating Mine Drainage Type Journal Article
Year 2005 Publication Mine Water Env. Abbreviated Journal
Volume 24 Issue 4 Pages 213-215
Keywords AMD prediction software
Abstract The U.S. Office of Surface Mining (OSM) is updating a popular software program that helps government agencies and mine water practioners predict what it will cost to treat acid mine drainage (AMD). Developers expect to release the update, AMDTreat Version 4.0, before the end of 2005. The new version will offer additional tools, expanded features, and a better user interface.
