Continuous Elution for Extraction of Gold from Carbon
26/11/2017 The continuous elution process is a continuous counter-current system operating in a pressure vessel at elevated pressure and temperature in which both carbon and the eluate are simultaneously moving through each other in opposite directions. During this process the carbon particles enter the top of the vessel loaded with gold and exit barren through the bottom, while

Carbon Elution/Strip System for precious metal recovery
During the standard elution process, the majority of the gold is recovered in the first half of the strip cycle and the remaining time is used to polish the carbon to low absorbed gold values. In our patented FLS-SVT Split-Zadra, as is true for the Split-AARL process, the solution from the polishing time is used as the lean eluate for the next elution cycle. The FLS-SVT Split-Zadra

Elution behaviour of metals from carbon
Many gold plants process ores containing traces of mercury, but the deportment of mercury through the entire plant under different operating conditions is poorly understood. It is known that generally mercury follows gold through the cyanide circuit (Zárate, 1985) and loads onto the activated carbon, but only partially elutes with the gold. This partial elution compounds the
