摘要：
In this paper, we present a mass transfer model that predicts two different mechanisms that control copper de-oxidation: (1) the transport of the reducing gas from the gas bubbles towards the melt/bubble interface, and (2) the transport of dissolved oxygen from the melt towards the melt/bubble interface. The model accounts for gas fluid flow and other process parameters such as lance submergence and nozzle diameter. The model was validated with published data and predictions from our model are in good agreement with the values reported. The key parameters to determine are the mass transfer coefficients of the reducing gas and that of the dissolved oxygen in the melt.
