    The key output of the chlorine refining process is silver chloride, which enters a silver leaching process to remove the base metals. The silver chloride is then reduced to metallic silver and is then refined by electrolysis. If there is demand in the market for a higher purity gold, then the 99.5% pure gold from the chlorine refining process is cast into anodes to be used in the electrolytic refining process, also
