Electrolytic recovery of gold from aqueous solutions
The recovery of gold from aqueous solutions using the clectrolytic reactor yields a high deposition rate. Despite low initial gold levels the reactor is effective in removing metal ions from solutions especially in the form of gold alloy deposits. Final gold concentrations as low as 0.1 mg 1-~ could be obtained.
