摘要:
A method of smelting copper includes: a generating step of generating blister and calcium ferrite slag from copper matte by charging the copper matte into a smelting furnace and oxidizing the copper matte; and a refining step of refining another blister from the calcium ferrite slag in an electrical furnace under a temperature condition of 1250 degrees C. to 1350 degrees C. and under a reductive atmosphere condition of oxygen partial pressure logPO2≦−9.3.
