elution rate carbons from gold ores

AARL Carbon Stripping System Operation: Elution and Electrowinning

Over the past year the gold extracted has averaged approximately 60 kg per day on a 365day per year basis. Carbon feed grades have varied between 4700 and 900 ppm withcorresponding final eluate as high as 500ppm gold but averaging nearer 200 ppm. Carbon

Ultrasonic elution of gold from activated carbon - ScienceDirect

Samples of plant loaded carbon in a CIL process were kindly supplied by an Australiangold mine. 100 g of the plant loaded carbon was washed with 1 l of distilled water, thenwashed with 1 l of 0.79 M HNO 3 at a rate of 5.0 BV per hour, in an attempt to remove

Continuous Elution for Extraction of Gold from Carbon

The continuous elution process is a continuous counter-current system operating in apressure vessel at elevated pressure and temperature in which both carbon and the eluateare simultaneously moving through each other in opposite directions. During this process

OPTIMIZING THE OPERATING CONDITIONS OF GOLD ELUTION AND ELECTROWINNING

Base metals that have not been stripped during the elution will build up in the carbonand will affect the gold loading in the CIP process. The continuous decrease of goldcontent in the stream and the variability of flow rate and temperature affect the elution
