Title:
ELECTRIC FURNACE OXYGEN-BLOWING SMELTING PROCESS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/021879
Kind Code:
A1
Abstract:
Provided are an electric furnace oxygen-blowing smelting process and system. The electric furnace oxygen-blowing smelting process comprises: in an electric furnace, carrying out oxygen-blowing smelting on an output of a copper concentrate smelting section, the output being copper matte, or a mixed melt of copper matte and smelting slag; and introducing an oxygen-containing gas into the electric furnace during the oxygen-blowing smelting, the oxygen volume content of the oxygen-containing gas being 20%-90%. According to the electric furnace oxygen-blowing smelting process of the present application, after the output of the smelting process in the previous section is introduced into the electric furnace, the function of the electric furnace is changed by blowing oxygen to the electric furnace, and the low-grade copper matte in the output is subjected to a blowing reaction to a certain degree in the electric furnace and then settled, thus improving the grade of the copper matte produced by the electric furnace, such that the obtained copper matte can meet the requirements of continuous blowing, so that a continuous blowing treatment can be achieved; in the addition, the electric furnace oxygen-blowing smelting process generates heat, which can supply the heat required by the electric furnace, so that additional energy consumption of the electric furnace required by electric heating is reduced.
