Although the standard process being well known for nearly one hundred years a significant increase of efficiency is possible even still today. For example the electrolyte should be prepared in an electrochemical way exclusively; beyond saving chemicals and expenditure of operations there are no outgoing air problems.

At the electrolysis installation itself progress can be made by using materials being fully resistant to corrosion accompanied by operational armatures standing the test. Moreover the application of cathode sheets for constantly repeated use, which are completely inert in these circumstances, may be profitable - the production of starting sheets is saved, and the stock of gold is reduced. 

Contamination of the cathode gold by AgCl - particles in suspension is prevented by repeatedly used anode bags. So the customary washing by ammonia with all its secondary problems is redundant. 

Concluding, electrochemical freeing the final electrolyte from gold guarantees beyond large environmental advantages, that absolutely no gold nor any precious metal belonging to the reduction group will remain within solution. By making easy the cycles of operation mentioned above costs are reduced, so that full amortisation within less than two years is normally possible.
