  Title Reduction of leachability of heavy metals in acid mine drainage Type Journal Article
  Year 1994 Publication J. Environ. Sci. Health Part A Environ. Sci. Eng. Abbreviated Journal  
  Volume 29 Issue 2 Pages 371-388  
  Keywords 1 Geography  
  Abstract The leaching characteristics of sludges from the treatment of acid mine drainage(AMD) from Iron Mountain Mine near Redding, California were compared using two different processes: caustic soda treatment and a modified lime/sulfide treatment process. The modified lime/sulfide process produced a sludge with better dewaterability characteristics than sludge from the caustic soda process. The results of the Cal WET indicated that the modified lime/sulfide process sludge had less leachability than that of sludge from the caustic soda process. Both processes could achieve a substantial reduction of heavy metals in leachate to levels below the federal regulatory limits(TCLP). For cadmium and zinc, however, neither process produced a sludge that met the requirements of the Cal WET procedure.
