Research progress in the simulation of oxygen bottom-blowing copper smelting

As an important pyrometallurgical copper smelting process, oxygen bottom-blowing copper smelting plays a key role and faces development difficulties. The sustainable development of the oxygen bottom-blowing copper smelting process is hindered by increasingly complex mineral resources, the urgent need to optimize large-scale equipment, and the high copper content in smelting slag. Simulation research featur low cost, high safety and good flexibility and has become an important method to solve the problem of oxygen bottom-blowing copper smelting. In this paper, the methods and characteristics of the simulation research of oxygen bottom-blowing copper smelting were introduced to analyze and summarize the status of stimulation in the reaction mechanism of oxygen bottom-blowing copper smelting, furnace flow and equipment improvement. Combined with the current development trends of oxygen bottom-blowing copper technology with complex raw materials, large-scale equipment, continuous bottom-blowing, and intelligent control, the future research direction of oxygen bottom-blowing copper smelting simulation is pointed out.
