  Course (Catalog) Description:

  Introduction to legal requirements for tailings and effluent disposal. Characterization of tailings. Tailings disposal methods. Tailings embankment design. Effluent treatment methods, acid mine drainage management. 

  (Prerequisites, consent of the instructor)

  Course Objectives:

  1. Know the legal frame of tailings and effluent disposal
  2. Propose a safe disposal method  tailings and the site of a tailings dam
  3. Evaluate tailings for acid rock drainage potential
  4. Know effluent and acid rock drainage (ARD) treatment methods

  
  

  Course Outcomes:
