The metallurgical efficiency of a Teniente Converter depends strongly on the degree of utilization of the oxygen enriched air, blown through tuyeres, during the smelting and converting reactions of the iron and copper sulfide minerals of copper concentrates that lead to the production of white metal. A mathematical model for calculating oxygen efficiency in Teniente Converters was developed. Based on the operating parameters of the reactor, the model allows for the prediction of the oxygen efficiency. The model takes into account the time for bubble formation and the time for bubble travel to the bath surface. Metallurgical reactions that consume oxygen occur during bubble formation and rise to the free surface. The results of the calculations agree fairly well with measurements performed in Teniente Converters.
