摘要
基于所构建的铜阳极炉精炼过程热力学仿真模型及系统,计算了某典型阳极炉精炼生产工况,验证模型热力学分析的可行性,进而考察气料比(RGF)、石英熔剂率(RFlux)和精炼温度(t)等工艺参数对产物组成及杂质分配行为的影响.结果表明:提高RGF、RFlux,可在一定程度上改变精炼渣组成,改善杂质入渣脱除效果,但因精炼渣量较小,除Co和Cr外其他杂质元素的实际入渣脱除率变化不大;提高温度对产物组分影响不大,但会降低杂质的脱除效果.综合工艺参数对阳极精炼过程的影响规律,得到的较优工艺参数为RGF为22 m3/t,RFlux为0.16%,t为1200℃.在此条件下,铜液的Cu品位、S含量和O含量分别约为99.39%、0.0065%、0.17%.
Abstract
Based on the thermodynamic simulation model and system of copper anode furnace refining process,a typical anode furnace refining production condition was calculated to verify the feasibility of the thermodynamic analysis of the model,and then the effects of process parameters such as gas-to-material ratio(RGF),quartz flux rate(RFlux)and refining temperature(t)on product composition and impurity distribution behavior were investigated.The results show that increasing RGF and RFlux can change the composition of refining slag and improve the removal effect of impurities into slag to a certain extent.However,due to the small amount of refining slag,the actual removal rate of other impurity elements except Co and Cr does not change much.Increasing the temperature has little effect on the product composition,but it will lead to a decrease in the removal of impurities.Based on the influence of comprehensive process parameters on the anode refining process,the optimum process parameters are RGF=22 m3/t,RFlux=0.16%,t=1200℃.Under this condition,the Cu grade,S content and O content copper liquid are about 99.39%,0.0065%and 0.17%,respectively.
