  • Zadra elution circuit Pyrometallurgy: Roasting, Smelting

    I gather it is a pressure Zadra elution, in which case your column temperature needs to get above 115C or rate will very slow. 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

  • AARL Carbon Stripping System Operation: Elution

    The Anglo American Research Laboratories AARL carbon stripping system used in this EXAMPLE has two definite advantages when compared with its most common counterpart, the Zadra system. It is much less expensive to operate and it produces a cleaner stripped carbon. It is however very reliant upon the availability of an abundant supply of good quality water and its water usage is far greater

    ELUTION BEHAVIOUR OF METALS FROM CARBON 475 Introduction Gold can be extracted industrially from ores by a variety of processes, and one of the most successful methods is the carbon-in-pulp (CIP) process. In CIP processing, ore is mined, ground, and leached with alkaline cyanidic solution to solubilize the gold as a gold cyanide complex. The

  • Chapter 33 Electrowinning ScienceDirect

    In the case of Zadra elution, where the electrowinning cell is in series with the elution column, the column and cell must be designed to elute and recover the gold by recirculation of the eluant until the gold content of the eluted carbon is low enough (<100 g/t) to be reactivated and returned to the adsorption circuit.

  • Modelling of the AARL elution process ScienceDirect

    The Zadra elution process makes use of pumping a hot (90) caustic cyanide solution with the loaded carbon in the elution column at atmospheric pressure. The eluate obtained is then treated in an electrowinning circuit where gold is removed. The barren electrolyte is returned to the elution column as eluant. This process exhibits slow kinetics taking at least 50 hours for a satisfactory elution

    A process is disclosed for the recovery of gold and/or silver values from activated carbon, wherein they are adsorbed as cyanide complexes. The process uses an eluant containing sugar. The process allows the eluant to pass through fresh carbon twice, thereby reducing the volume of the gold-loaded eluant. This, in turn, reduces the size of the electrowinning or zinc precipitation circuits.
