Sažetak

The article presents the results of constructing a diagram of the phase composition of the Fe-S-Cu system and its mathematical model. Using the equations obtained in the work, a computer program was created and, using it, an analysis of phase formation in copper ores of various deposits was carried out. It was found that copper ore concentrates from the Berezovsk deposit in Kazakhstan contain Cu₅FeS₄ (20,22 %), CuS (14,21 %) and FeS₂ (65,57 %), and copper ores from the Zyryanovsk deposit contain CuFeS₂ (4,03 %), Cu₅FeS₄ (45,29 %) and FeS₂ (50,68 %). Such data allows you to choose the optimal methods for further processing of concentrates, and the mathematical approach itself is more productive than the often used geometric one according to the rule of segments.
