Abstract: Mathematical model for mass transfer of chemical reactions on the surface of the smelting bath pit in oxygen top-blown smelting furnace was put forward. Additionally, one of two mathematical models for mass transfer of chemical reactions forming copper matte in smelting bath and the other for parameters of smelting process were developed. The verification tests were simultaneously carried out in a pilot scale furnace and the experimental results show that these mathematical models are convincing. Thus, these numerical models are reliable to simulate pyritic smelting process for copper-nickel mineral in oxygen top-blown furnace.
