The method just described aims at leaving gold in an insoluble state at the anode Other impurities are usually left there and the gold sponge or slimes needs further refining by methods to be indicated later By using a suitable electrolyte the gold can be dissolved from the anode bars and deposited in sheet form on the cathode while many metals can be left in solution The active agent.
This system includes a very simple to use test kit that will detect as little as four parts of gold per million parts of solution ensuring that no dissolved gold is lost 99 95 purity Even if you have no prior experience refining the metals yielded by the SaltSystem is always of 99 95 or greater purity.
