Embodiment 1
[0018] The main components and contents of black copper mud and arsenic-containing dust are shown in Table 1 and Table 2:
[0019] The main component and content wt% of table 1 black copper mud
[0020] Cu As Sb Bi Pb Ni 42 22.5 6.2 2.3 0.7 0.5
[0021] Table 2 Main components and content wt% of arsenic-containing smoke dust
[0022] As Pb Fe Cu Zn 25.3 20.2 9.8 0.4 7.5
[0023] According to the mass ratio M 黑铜泥 :M 含砷烟尘 :M 硫酸钠 = 1:1:10 ratio Mix the three materials evenly, heat to 1000°C for high-temperature melting, keep warm for 5 hours, and separate layers after melting. After the reaction, the materials are divided into two layers, and the upper layer is a mixture containing arsenic and sodium. material; the lower layer is blister copper with yellow metallic luster, which is used for electrolytic refining of copper. Through detection and analysis, the recovery rate of blister copper is 90.7%, and the copper...
Embodiment 2
[0025] Black copper mud, arsenic-containing smoke and dust are consistent with embodiment 1.
[0026] According to the mass ratio M 黑铜泥 :M 含砷烟尘 :M 硫酸钠 =2:1:3 ratio Mix the three materials evenly, heat to 1200°C for high-temperature melting, keep warm for 2 hours, and separate layers after melting. After the reaction, the materials are divided into two layers, and the upper layer is a mixture containing arsenic and sodium. material; the lower layer is blister copper with yellow metallic luster, which is used for electrolytic refining of copper. Through detection and analysis, the recovery rate of blister copper is 90.5%, and the copper content in the blister copper is 99.3%.
Embodiment 3
[0028] The main components and contents of black copper mud and arsenic-containing dust are shown in Table 3 and Table 4:
[0029] The main component and content wt% of table 3 black copper mud
[0030] Cu As Sb Bi Pb Ni 51.5 17.9 1.9 1.8 0.6 0.6
[0031] Table 4 Main components and content wt% of arsenic-containing smoke dust
[0032] As Pb Cu Zn Bi 8.4 26.9 3.1 11.7 2.2
[0033] According to the mass ratio M 黑铜泥 :M 含砷烟尘 :M 硫酸钠 = 1:5:12 ratio Mix the three materials evenly, heat to 1300°C for high-temperature melting, keep warm for 1 hour, and separate layers after melting. After the reaction, the materials are divided into two layers, and the upper layer is a mixture containing arsenic and sodium. material; the lower layer is blister copper with yellow metallic luster, which is used for electrolytic refining of copper. Through detection and analysis, the recovery rate of blister copper is 90.1%, and the coppe...
