The loaded carbon is recovered via a carbon recovery screen and treated in the elution and electrowinning circuit. Loaded carbon is acid washed with dilute hydrochloric acid in an 18 t acid wash column prior to transfer into an elution column where it is presoaked in a cyanide/caustic solution for 30 minutes to elute gold. The pregnant eluate is then rinsed from the carbon by as many as 10 bed

For example, for a sample with 20% of –300 μm material in the feed, if this is not scalped out of the fresh feed, then the mill charge, at 250% circulating load will contain / or % of –300 μm in the mill charge compared with 0% for a scalped fresh feed, at a closing screen of 300 μm. This should not have a great influence on the production of new fines unless the test was

The slurry is pumped to the loaded carbon screen where the carbon is screened from the slurry, which is returned to the tanks. Spray bars fitted to the screen wash residual slurry from the carbon. The carbon discharges off the end of the screen into the elution column. This is done in a batch process with six tonnes of carbon being treated each strip. When the elution column is full of carbon

From the first tank, the loaded carbon is pumped using a recessed impeller pump (to not degrade the carbon), or another suitable type of pump, to a loaded carbon screen, where the slurry passes through the screen and retains the carbon.
