    • Fire-refined blister copper is produced from copper concentrate by a process comprising: (A) melting and oxidizing the copper concentrate in a smelting furnace (17) to produce molten matte and slag, and to separate one from the other; (B) removing the molten matte from the smelting furnace (17); (C) solidifying the molten matte; (D) injecting the solidified matte into a converting furnace (33) in which the matte is converted to blister copper and slag; and (E) transferring the blister copper from the converting furnace to an anode furnace (47a and 47b) to produce fire-refined blister copper. After the fire-refined blister copper is produced in the anode furnace, it is typically transferred to an anode casting wheel (66) on which it is converted to copper anodes suitable for subsequent electrolytic refining to cathode copper.
    • 通过以下方法由铜精矿生产火焰精炼的水泡铜,该方法包括:(A)在冶炼炉(17)中熔化和氧化铜精矿以产生熔融的无光泽和熔渣,并将另一个分离; (B)从冶炼炉(17)中除去熔融的哑​​光; (C)固化熔融哑光; (D)将固化的锍注入转化炉(33)中,其中锍转化为铜和熔渣; 和(E)将所述泡罩铜从所述转化炉转移到阳极炉(47a和47b)以产生防火精制泡罩铜。 在阳极炉中产生火焰精炼的水泡铜之后,通常将其转移到阳极铸造轮(66)上,在其上将其转化成适用于随后的电解精炼至阴极铜的铜阳极。
