Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

The fire refining of blister copper is an important link in the copper smelting process, and the aim is to remove impurity elements in blister copper as much as possible so as to meet the requirements of electrolytic refining on the chemical components of anode plates. The fire refining of blister copper mainly involves oxidation and reduction. The oxidation stage is to send oxidant into molten crude copper at high temperature to oxidize part of copper in the copper liquid to generate cuprous oxide, and then to react with impurities in the copper liquid to deeply oxidize the impurities to form refined slag. After the oxidation is finished, the refining slag floating on the surface of the copper liquid is required to be scraped. And then enters a reduction stage, wherein a reducing agent is fed into the copper liquid at high temperature, and cuprous oxide generated in the copper liquid in the oxidation stage is reduced into copper.
At present, when the refining slag is deslagging, because the oxidation-reduction port arranged at the lower part or the bottom of the furnace body side needs to be continuously introduced with an oxidant and a reducing agent so as to ensure that the oxidation-reduction port is not filled with copper liquid backward, the copper liquid is still in a stronger stirring state in the deslagging process, the refining slag cannot be thoroughly scraped clean, the finally produced copper has poorer quality, and the problem is more obvious in treating high-impurity blister copper.
For the problem of poor quality of copper produced by the existing fire refining method, the inventor further finds that the impurity elements reenter the copper liquid in the practical process because the refining slag remained in the copper liquid is reduced in the reduction stage, thereby affecting the quality of the produced copper.
