The invention provides a method for producing anode copper. The production method comprises the following steps: conveying copper matte into a copper-making furnace, and spraying oxygen-enriched air into the copper-making furnace to carry out oxidation treatment on the copper matte so as to lead the copper matte to have a copper-making reaction to generate anode copper, wherein the volume percentage of oxygen in the oxygen-enriched air is 30-80%. According to the method provided by the invention, copper matte is oxidized in a state of a highly oxygen-enriched environment, so that a copper-making reaction occurs on the copper matte, and the copper matte can be converted into anode copper in one step, thereby greatly simplifying the production process of anode copper, improving the production efficiency of anode copper and saving the production cost. 本发明提供了种阳极铜生产方法。该生产方法包括以下步骤：将铜锍输送至造铜炉中，并在造铜炉中喷入富氧空气对铜锍进行氧化处理，以使铜锍进行造铜反应，生成阳极铜；其中，富氧空气中氧气的体积百分比为30～80％。本发明在高富氧状态下对铜锍进行了氧化处理，使其发生造铜反应，步即可从铜锍转变为阳极铜，大大简化了阳极铜的生产工艺，提高了阳极
