This article discusses the development of a technology for producing nickel- and chromium-containing ferroalloy through the carbothermic reduction of low-grade ores from the Batamsha deposit. Thermodynamic modeling of phase formation was carried out using the Chemistry 10 software package, along with a series of pilot-scale smelting experiments in a submerged arc furnace. The influence of technological parameters, particularly slag basicity, on the distribution of nickel and chromium in the alloy was studied. The results of an X-ray phase analysis confirmed the modeling conclusions, revealing the presence of nickel and chromium silicide phases. The proposed technology demonstrated a high metal recovery rate and process stability, indicating its potential for industrial application in Kazakhstan.
