The temperature dependences of the viscosity of the slags of the autogenous smelting of copper–zinc concentrates have been determined. The activation energies of viscous flow and the temperature of the onset of solidification of the molten slags are calculated. The influence of the suspension (magnetite) and emulsion (matte) components on the slag viscosity has been estimated. The sedimentation of the molten slags, especially in the case of a high copper content in them, makes it possible to separate the part of dispersed matte sulfide particles into a bottom phase. The results obtained can be used to optimize slag compositions and to decrease the copper losses.

铜锌精矿自熔冶炼炉渣的粘度

已经确定了铜锌精矿自熔冶炼炉渣粘度的温度依赖性。计算了粘性流的活化能和熔融炉渣开始凝固的温度。估计了悬浮液（磁铁矿）和乳化液（无光泽）成分对矿渣粘度的影响。熔融炉渣的沉淀，特别是在炉渣中铜含量高的情况下，可以将分散的无光泽硫化物颗粒的一部分分离成底相。获得的结果可用于优化炉渣成分并减少铜损。
