Embodiment 1
[0045] The chemical composition of lead matte in a factory is as follows:
[0046] Pb: 7.83%, Cu: 29.38%, Fe: 36.22%, S: 20.07%, SiO 2 : 3.81%, CaO: 1.14%, Ag: 0.0993%, Zn: 1.11%, Te: 0.11%, Se: 0.21%. Implementation methods such as figure 1 As shown, after grinding the lead matte through an 80-mesh sieve, add the prepared FeCl 3 The leaching solution is fed into the air, the stirring speed is 300r / min, and the leaching is carried out under normal pressure. The leaching conditions are: using FeCl 3 Solution leaching, FeCl 3 The concentration is 300g / L, the liquid-solid ratio is 5:1, the temperature is 89°C, air is continuously fed in, the stirring speed is 300r / min, and the reaction time is 4 hours. The recovery rate of copper is 84.39%.
Embodiment 2
[0048]The chemical composition of lead matte in a factory is as follows:
[0049] Pb: 7.83%, Cu: 29.38%, Fe: 22.60%, S: 19.85%, SiO 2 : 3.02%, CaO: 1.54%, Ag: 0.1022%, Te: 0.19%, Se: 0.31%. Implementation methods such as figure 1 As shown, after grinding the lead matte block material, add the prepared FeCl 3 Leaching liquid, and feed into air, stirring speed is 500r / min, normal pressure leaching, the operation of leaching copper is exactly the same as embodiment 1, and its leaching condition is: adopt FeCl 3 Solution leaching, FeCl 3 The concentration is 350g / L, the liquid-solid ratio is 5:1, the temperature is 95°C, air is continuously introduced, the stirring speed is 350r / min, and the reaction time is 8 hours. The recovery rate of copper is 88.07%.
Embodiment 3
[0051] The chemical composition of lead matte in a factory is as follows:
[0052] Pb: 7.67%, Cu: 29.72%, Fe: 19.53%, S: 20.08%, SiO 2 : 4.52%, CaO: 0.97%, Ag: 0.0633%, Te: 0.17%, Se: 0.26%. Implementation methods such as figure 1 As shown, after grinding the lead matte block material, add the prepared FeCl 3 Leach solution, and feed into air, stirring speed is 300r / min, normal pressure leaching, the operation of leaching copper is exactly the same as embodiment 1, and its leaching condition is: adopt FeCl 3 Solution leaching, FeCl 3 The concentration is 400g / L, the liquid-solid ratio is 5:1, the temperature is 95°C, air is continuously fed in, the stirring speed is 300r / min, and the reaction time is 7.5 hours. The recovery rate of copper is 92.6%.
