Embodiment 1
[0018] The main ingredients and content of black copper paste and arsenic and dust are shown in Tables 1 and 2:
[0019] Table 1 Main ingredients and content of black copper paste and wt%
[0020] Cu AS SB BI PB Ni 42 22.5 6.2 2.3 0.7 0.5
[0021] Table 2 Main ingredients and contents of arsenic and dust
[0022] AS PB FE Cu Zn 25.3 20.2 9.8 0.4 7.5
[0023] By quality ratio M 黑铜泥 : M 含砷烟尘 : M 硫酸钠 After mixing the three materials, the three materials were mixed, heated to 1000 ° C for high temperature smelting, holding 5 h, after the smefry was completed, and the reaction was divided into two layers, the upper layer was a mixture of sodium containing sodium The lower layer is a thick copper with yellow metallic gloss, used for electrolysis refining of copper. The recovery of the crude copper was 90.7%, and the content of copper in the crude copper was 99.1%.
Embodiment 2
[0025] Black copper paste, arsenic and dust containing the same as in Example 1.
[0026] By quality ratio M 黑铜泥 : M 含砷烟尘 : M 硫酸钠 After mixing the three materials, the three materials were mixed, heated to 1200 ° C for high temperature smelting, holding 2 h, after the smefry was completed, and the reaction was divided into two layers, the upper layer was a mixture of sodium containing sodium The lower layer is a thick copper with yellow metallic gloss, used for electrolysis refining of copper. The recovery of crude copper was detected was 90.5%, and the content of copper in the crude copper was 99.3%.
Embodiment 3
[0028] The main components and content of black copper paste and arsenic and dust are shown in Table 3 and Table 4:
[0029] Table 3 Main ingredients and content of black copper paste wt%
[0030] Cu AS SB BI PB Ni 51.5 17.9 1.9 1.8 0.6 0.6
[0031] Table 4 Main ingredients and contents of arsenic smoke and wt%
[0032] AS PB Cu Zn BI 8.4 26.9 3.1 11.7 2.2
[0033] By quality ratio M 黑铜泥 : M 含砷烟尘 : M 硫酸钠 After mixing the three materials, the three materials were mixed, heated to 1300 ° C for high temperature smelting, thermal temperature 1 h, after the smefry was completed, and the reaction was partially separated, the upper layer was a mixture of sodium containing sodium The lower layer is a thick copper with yellow metallic gloss, used for electrolysis refining of copper. The recovery of crude copper was detected was 90.1%, and the content of copper in the crude copper was 99.2%.
