Refractory Gold The last type of gold deposit is called refractory gold and it is the most difficult type to extract It can be defined as any ore that responds poorly to a conventional gravitycyanidation process with examples including copper porphyry complex sulfides arsenopyrite and leadzinc associations 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
