摘　　要：用多元回归和Ｂｕｔｌｅｒ方程分别计算了金川镍闪速炉熔炼渣和冰镍的表面张力．运用 Ｇｉｒｉｆａｌｃｏ－Ｇｏｏｄ方程，计算了金川镍闪速炉熔炼渣与冰镍间的界面张力，分析了界面张力与炉渣 成分、表面张力及温度的关系．提出了改进金川镍闪速炉冶炼工艺的若干建议．Surface tensions of slag and matte in Jinchuan nickel flash smelting process were respectively calculated by the way of Butler equation and polynomial fit. Based on Girifalco-Good equation interfacial ten- sions between slag and matte were calculated. The relationship between interfacial tension and slag composi- tion、surface tension as well as temperature was discussed. Some advice for decreasing the noble metal loss in Jinchuan nickel flash smelting process slags was given.
