The submerged lance smelting furnace (SLS) for copper smelting has been developed and used by Dongying Fangyuan Nonferrous Metals Co., Ltd. The technology has shown advantages such as high oxygen enrichment, good feeds adaptability, short process time, high SO2 content, and auto-thermal operation. In this study, computational fluid dynamics (CFD) was used to investigate the gas/matte two-phase flow characteristics and the chemical reactions in the SLS during the typical operating conditions. The Eulerian-Eulerian approach was employed to model the phase interactions. The inner phase and interphase chemical reactions were modeled by calculating the mass transfer coefficients. The simulation was conducted using commercial software ANSYS Fluent. The developed CFD model is able to predict the flow, temperature, and species distributions inside the SLS under various operating conditions.
