Elution of gold from carbon by the micron solvent distillation

The desorption of gold from activated carbon is promoted byanic solvents to At 6580°C the elution of gold is fast and is not affected by water quality. The carbon retains a highic activity after solvent stripping which is slightly better on carbon, stripping withanic solvents and electrowinning.
