The purpose of this report is to provide information on cyanide treatment methods for heap leaches and tailings activities associated with cyanidation operations, including disposal units that receive wastes from such operations. The agency has collected this information for use in regulatory agencies and the mining industry to better understand treatment options; however, the agency has not evaluated the efficiency of the methods discussed. The report discusses cyanide detoxification or treatment in terms of chemistry, duration, removal efficiencies, and advantages and limitations. After a discussion of treatment techniques, the report describes typical closure and reclamation activities for heaps and tailings impoundments, identifying issues that are still outstanding. The report also describes Federal and state requirements that apply to cyanide operations. In addition, selected case studies, chosen to reflect a range of facility types, are presented.
