Zadra Elution Column

Zadra elution circuit - Pyrometallurgy: Roasting, …

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. Eluant flowrate is not too critical in the 2-4 BV/h range. You should be achieving optimum elution with about 30 BV of eluant …

Modelling of the AARL elution process - ScienceDirect

01/05/1994· There are two main types of elution processes and these are the Zadra and the AARL elution variant. 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 …
