The oxygen-rich bath smelting process of copper dross was simulated using Factsage software. It was found that the two-step simulation results agreed better with the industrial data, especially in the speiss. Bi, Pb, Sb, As, and Cu contents in the speiss by two-step simulation differed from the industrial data by 0.6 wt.%, 0.8 wt.%, 2.6 wt.%, 7.2 wt.%, and 8.6 wt.%, respectively. Two-step simulation results indicated that the speiss partitioning of Sb, As, and Cu increased from 60.1%, 32.3%, and 27.5% to 81.6%, 67.8%, and 47.2%, respectively, with the smelting temperature increasing from 1050 °C to 1250 °C. While the metal partitioning of Sb and Cu increased from 0% and 2.7% to 15.2% and 13.3%, respectively, with the separation temperature increasing from 400 °C to 700 °C.

铜渣浴熔炼过程多步热力学计算

利用Factsage软件模拟了铜渣富氧熔池冶炼过程。发现两步模拟结果与工业数据更吻合，尤其是在speiss。通过两步模拟，矿藏中的 Bi、Pb、Sb、As 和 Cu 含量与工业数据相差 0.6 wt.%、0.8 wt.%、2.6 wt.%、7.2 wt.% 和 8.6 wt.% ， 分别。两步模拟结果表明，随着熔炼温度从 1050 °C 升高，Sb、As 和 Cu 的 speiss 分配分别从 60.1%、32.3% 和 27.5% 增加到 81.6%、67.8% 和 47.2%到 1250°C。而随着分离温度从 400 °C 增加到 700 °C，Sb 和 Cu 的金属分配分别从 0% 和 2.7% 增加到 15.2% 和 13.3%。
