Fouling of carbon regeneration and Elution Gold Metallurgy Apr 02 2016· Elution of gold from carbon Over the last 10 years there has been much research and development into elution procedures all trying to improve on the traditional Zadra Process 37 which takes days to complete

The stripping of gold from loaded carbon here involves two basic steps Acid Washing and Elution The elution step may be further divided into two major stages carbon preheat and elution proper Here a separate column is provided for acid washing

The next step is the elution of adsorbed gold from activated carbon with an efficient eluant Mainly three methods of elution are used in industry I The Zadra process II The Anglo American Research Laboratory AARL method III The use of organic solvents such as acetonitrile or methanol

for manufacturing elution column for processing of gold AARL Carbon Stripping System Operation Elution During this stage a 2 caustic3 cyanide solution mixture is recirculated through the loaded carbon in the elution column until such time as a predetermined “top of column” temperature is reached

Elution of AM2B resin is similar to that of Minix but a longer elution time seems to be required Bolinsky and Shirley 1996The process includes a series of elutions contacting the loaded resin with different solutions The elution flowsheet differs from plant to plant and some of the steps described below are optional

gold elution plant 3 Many methods are used commercially for recovering gold and silver from loaded activated carbon The major processes include 1 Atmospheric Zadra Stripping 2 Pressurized Zadra Stripping 3 Anglo American Research Laboratory AARL Method 4 Alcohol Stripping 5 Micron Elution Procedure

Elution Column Gold Processing Elution In Gold Processing For manufacturing elution column for processing of goldor manufacturing elution column for processing of gold prompt caesar is a famous mining equipment manufacturer well known both at home and abroad major in producing stone crushing equipment mineral separation equipment limestone grinding et Read More
