Liquid-Liquid Extraction for Acid Mine/Acid Rock Drainage Processing for Water Purification and Recovery of Sulfate and Metals Without Sludge or Brine Production
This paper presents the results of bench- and field-pilot development and demonstration testing of an innovative application of liquid-liquid extraction (LLX) technology for the removal of metals and sulfate from acid mine and acid rock drainage (AMD, ARD), and, importantly, within the process, the metals and sulfate are recovered as valuable co-products. These co-products have commercial value that can offset the cost of water purification. The process is not limited to AMD/ARD waters – other waters with metals and sulfates can be processed using this technology. The initial process development has been for AMD, and this paper presents those results.
