The blister copper is a copper intermediate product smelted by taking copper concentrate as a raw material, generally has 98% -99% of copper content, and is a raw material for producing cathode copper by electrolysis. The process for producing anode copper by the pyrometallurgy of copper concentrate generally firstly carries out sulfur-making smelting on copper sulfide concentrate to obtain copper sulfur, then sends the copper sulfur into a converting furnace for converting into blister copper, and the blister copper is desulfurized and deoxidized by the anode furnace to obtain the anode copper with the purity of 99.5 percent. With the technical progress, the converting process has realized the technological improvement from intermittent converting to continuous converting, and the anode refining furnace still needs intermittent operation due to the processing technology and cannot continuously produce. Under the process, a blister copper charging chute is needed to connect the converting furnace with the anode furnace.
The sulfur content of the blister copper produced by the continuous converting process is often high, and for example, the sulfur content of the blister copper produced by the top-blown furnace can be as high as more than 0.5%, so that the subsequent anode refining needs strong desulfurization. While the compressed air flow during anodic furnace oxidation is smaller, typically at 1000nm 3 About/h, the oxidation time is often more than 5 h. The oxidation time of a single furnace is longer, the copper discharge time of a top-blown furnace is delayed, and the dynamic balance risk of melt blowing is influenced, so that the productivity is restricted.
