processing of gold equesion

This causes gold to collect on the negative terminals Smelting which results in nearly pure gold involves melting the negative terminals in a furnace at about 2100 degrees F 1149 degrees C When workers add a chemical mixture known as flux to the molten material the gold separates from the metal used to make the terminals Workers pour off the flux and then the gold
