Proposed is an algorithm for calculating heat and mass transfer in electrothermal ore recovery processes in non-ferrous metallurgy. To implement the algorithm, the finite element method was used, which allows to take into account complex configuration of the internal volume of the reactor. A finite element grid automatic construction algorithm was used. An iterative algorithm for the finite element equations implementation with the matrix width optimization and the use of symmetry properties is proposed. A set of programs that allows to calculate operating modes of electrothermal ore-smelting reactors of any design, including those used in the smelting of non-ferrous metal alloys, has been developed. The interface of the programs is user-friendly. The multi-document interface provides visualization of the calculation results in the form of isolines of temperature fields and velocity vectors.

The work was carried out as part of the State task, project No. FSWF-2020-0019.
