Iron Reduction from Concentrates of Hydrometallurgical Dressing

The article presents results of theoretical and experimental studies the processes iron solid-phase reduction from an iron-containing concentrate obtained as a result hydrometallurgical dressing ferromanganese polymetallic manganese-containing ores with coals grades D (long-flame) 2B (brown). method thermodynamic modeling using TERRA software complex was used to study reducing properties hydrocarbons by calculating equilibrium compositions in temperature range 373–1873 K. authors dependences volume gas phase formed release volatile components during heating on for under consideration. As modeling, optimal temperatures consumption are determined, which ensure complete concentrate. were modern research methods laboratory analytical equipment, well statistical processing. Results analysis carried out Setaram LabSys Evo thermal analyzer showed that process decomposition studied proceeds according general laws. long-flame coal less intensively than brown coal. agents have shown volumes phases, when heated 1173 K argon atmosphere, practically coincide calculated values. study, is determined at 1473 best agent minimum specific grade. When determining amount charge mixtures metallization processes, it found excess agent, possible achieve almost extraction (98–99%)
