  Title Use Of Cellulosic Substrates For The Microbial Treatment Of Acid-Mine Drainage Type Journal Article
  Year (up) 1994 Publication Journal of Environmental Quality Abbreviated Journal  
  Volume 23 Issue 1 Pages 111-116  
  Keywords mine water treatment  
  Abstract A mixed aerobic-anaerobic microbial treatment process was developed previously for acid mine drainage (AMD) using straw as a substrate. The process was effective only if AMD was supplemented with sucrose. The present study was conducted to determine which, if any, of three cellulosic materials could sustain the microbial treatment of AMD without the addition of a sucrose amendment and to determine the effect of the retention time on the performance of the reactors. The performance of small reactors that treated simulated AMD in the continuous mode was evaluated using alfalfa (Medicago sativa L.) hay, timothy (Phleum pratense L.) hay, and straw with a 5 d retention time. Parameters measured were pH, Fe, Al, sulfate, and ammonium. Timothy hay and straw sustained AMD mitigation for 3 wk, and thereafter all activity ceased. After the reactors ceased treating AMD, the mitigative activities were reinitiated by the addition of sucrose, but not by urea. Alfalfa sustained AMD mitigation for a longer time period than either straw or timothy. The effect of three retention times, 3.5, 7, and 35 d, was then investigated for reactors containing fresh alfalfa. Increasing the retention time resulted in better metal removal and a greater pH increase. With a 7-d retention time, 75 L of simulated AMD were neutralized from a pH of 3.5 to a pH value greater than 6.5. Reactors operating with a 3.5-d retention time treated only 58.3 L of simulated AMD before failing. Ammonium was detected in effluents of active reactors. The results of this study indicate that a low maintenance microbial treatment system can be developed with alfalfa as a substrate without the addition of a sucrose amendment.

  Abstract In the report, wetland technology is described in which the main reactive layer is limestone gravel (rather than organic material) which is overlain by a fine gravel filter and soil. The three-year project included laboratory and field studies. Vertical aerated wetlands, simulated by columns, constructed in the field and in the laboratory, were operated during the project. The report presents a summary of results given in previous reports and summaries of results obtained using water from Butte, MT, and field studies at the Rockford Tunnel, near Idaho Springs, CO.

  Title The Golden Cross Mine water management system Type Journal Article
  Year (up) 1994 Publication New Zealand Mining Abbreviated Journal  
  Volume 14 Issue Pages 15-21  
  Keywords Australasia Coromandel Peninsula cyanides gold ores Golden Cross Mine metal ores mines New Zealand North Island tailings Waihi New Zealand waste water water management water treatment 30, Engineering geology  
  Abstract Because of its location in the sensitive Coromandel Peninsula, strict water management and environmental requirements had to be met on the Golden Cross Mine Project. This led to the development of new technologies for cyanide recovery and the adoption of advanced water management and water treatment systems. This paper discusses the water management and treatment system adopted for contaminated water at Golden Cross. While permit discharge levels must be and are met for mine discharge waters, the ultimate success of the water management system is demonstrated by the results downstream; biological surveys show no changes to the resident aquatic life in the river.
