Modelling of the AARL elution process - ScienceDirect

1994-5-1  This process exhibits slow kinetics taking at least 50 hours for a satisfactory elution. This led to the development of the AARL process. The AARL process makes use of hot acid treatment of the loaded carbon with 3 % HCI solution for 30 minutes before presoaking in hot caustic cyanide solution at 100 - 120 for at least 30 minutes.

Carbon Stripping – Denver Mineral Engineers

With the AARL process, elution is normally proceeded by acid washing the carbon. Acid washing is used with all of the other stripping systems, but it is mentioned specifically with the AARL procedure, because AARL systems generally use the stripping vessel to acid wash and acid washing is, therefore, controlled as part of the stripping sequence ...
