Abstract Smelting with oxygen bottom blowing is one of the main methods used in the frame of copper pyrometallurgy. With this approach, feed materials and oxygen-enriched air are introduced in reversed order to enhance multiphase flow within the furnace. Understanding the flow structure and temperature distribution in this setup is crucial for optimizing production. In this study, gas-liquid interactions, and temperature profiles under varying air-injection conditions are examined by means of numerical simulation for a 3.2 m × 20 m furnace. The results indicate that the high-velocity regions are essentially distributed near the lance within the… More >
