  • Zadra elution circuit - Metallurgist & Mineral Processing Engineer

    Water quality is very critical for AARL elution, not so much for Zadra, but you should still use the best quality available for eluant make-up. Not process water. E/W single pass efficiency is critical for Zadra because gold not recovered is then re-circulated back to the elution column, slowing down the elution rate.

  • 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 ...

  • difference between zadra and aarl process

    The old debate of Zadra versus AARL is hopefully over. The use of Zadra systems was a significant contributor to the negative view of using carbon for silver recovery. The AARL elution process has the advantage of a short elution time (3 hours) compared with the 12-24 hours for Zadra. Clearly the AARL ….

  • Processing of high-silver gold ores - ScienceDirect

    Although plants have successfully operated with elutions at 110°C, it is most common to design an elution circuit that is capable of operating at 120–130°C. This means that separate columns are required for elution and acid washing because the butyl rubber lining frequently used in AARL columns is not suitable at these temperatures.
