摘　　要：金川集团公司沉降电炉弃渣有价金属含量高且熔化温度高。采用SEM-EDS与XRD确定了镍和铜在渣中的主要损失形式为夹杂或悬浮。测定了以Ausmelt熔炼渣为基础的半合成渣的熔化温度,研究了Fe/SiO2及CaO含量对半合成渣熔化温度的影响。结果表明,当Fe/SiO2=0.9～1.0且CaO含量为6%～10%时,渣的熔化温度明显降低,为Ausmelt炉镍熔炼工艺参数的优化提供参考。The discarded slag of Jinchuan electric settling furnace （ESF） contains high content valuable metal with high melting temperature. The main form of nickel and copper loss in slag is manifested through SEM-EDS and XRD. The melting temperature of semi synthetic slag, basically Ausmelt smelting slag, was measured. The effects of Fe/SiO2 ratio and CaO content on melting temperature of semi-synthetic slag were investigated. The results show that the melting temperature of slag declines significantly when Fe/SiO2 ratio is 0.9-1.0 and CaO content is 6%-10%. The results can provide optimized process parameters for Jinchuna nickel Ausmelt smelting.
