what is elution in gold processing - casafloramieke

elution column gold processing - KB T. Elution time and elution volume. The "elution time" of a solute is the time between the start of the separation (the time at which the solute enters the column) and the time at which the solute elutes.In the same way, the elution volume is the volume of eluent required to cause elution.

Elution - Wikipedia

In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent; as in washing of loaded ion-exchange resins to remove captured ions.. In a liquid chromatography experiment, for example, an analyte is generally adsorbed, or "bound to", an adsorbent in a liquid chromatography column. The adsorbent, a solid phase (stationary phase ...

US6200364B1 - Process for eluting precious metals from ...

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. The process also improves elution efficiency when barren electrowinning solution is recycled in the elution process.

Ion Exchange Australia

The ion exchange process includes three major stages: sorption of valuable or unwanted ions, desorption (or elution) and washing. An addition stage - regeneration - could be used in case when the IX resin needs to change a from after elution. The operation of the ion exchange processes can be conducted in either cyclic (batch) or continuous mode.

Tau Lekoa stream uses the Zadra process. The eluant is continuously circulated through the column and an electrowinning cell in series. A caustic cyanide solution, normally 0.2 to 0.5 % NaCN and 2% NaOH, is pumped to the elution column and is pre-heated by the solution leaving the column. The temperature is further raised by a steam heat exchanger.
