Through this process, gold is brought to 9999 purity. The gold anode is placed in a solution of hydrochloric acid and gold chloride. An electric current is emitted, dissolving the anode while Gold plates onto a titanium cathode and impurities settle at the bottom. Final pour. The resulting pure gold is then poured into bars, coins, and grain.
