METHOD OF REDUCING IMPURITIES IN MOLTEN GOLD USING FUMING

摘要

PURPOSE: A method of reducing impurities in molten gold using fuming is provided to reduce the content of impurities within gold ingot by reducing impurities in molten gold through fuming. CONSTITUTION: A method of reducing impurities in molten gold using fuming comprises steps of: preparing gold ingot formed of gold containing impurities(S10), melting the gold ingot to obtain molten gold(S20), injecting gas into the molten gold so as to induce fuming for reducing the content of impurities in the molten gold(S30), and solidifying the molten gold(S40).
