摘　　要：为强化铜渣贫化回收渣含铜,设计了一种强化铜渣贫化的还原剂。采用HSC 6.0热力学软件计算对比了新型贫化剂与无烟煤、黄铁矿等常用贫化剂贫化熔炼渣回收铜锍的反应,并以某冶炼厂熔炼渣为原料进行试验并验证了新型贫化剂的强化作用。热力学计算结果表明,新型贫化剂还原铜渣(主要成分为Fe_(2) SiO_(4)和Fe_(3) O_(4))的效果优于无烟煤和黄铁矿。试验结果表明,采用无烟煤、黄铁矿、新型贫化剂三种还原剂单独贫化回收渣含铜时,铜的回收率分别为30.83%、52.50%、66.67%。新型贫化剂能够强化回收渣含铜,有望为铜渣高效贫化并提高无烟煤等传统化石能源贫化铜渣利用率提供借鉴。In order to enhance the recovery of copper from copper slag,a reductant for strengthening copper slag dilution was designed.The reaction of copper matte recovery from smelting slag with novel-style reductant and commonly used dilution agents such as anthracite and pyrite was calculated and compared by HSC 6.0 thermodynamic software.The smelting slag of a smelter was used as raw material to test and verify the strengthening effect of novel-style dilution agent.The thermodynamic calculation results demonstrate that the novel-style reductant exhibits superior effectiveness on reducing copper slag(the main components of Fe_(2) SiO_(4) and Fe_(3) O_(4))is better than that of anthracite and pyrite.Experimental results show that the recovery rates of copper are_(3)0.83%,52.50%and 66.67%,respectively,when anthracite,pyrite and novel-style reductant are used to reduce copper in slag alone.The novel-style reductant can significantly strengthen copper recovery from slag,and it is expected to provide reference for the efficient dilution of copper slag and improve the utilization rate of traditional fossil energy such as anthracite.
