System and method for low-carbon electrometallurgy of iron ore
The invention belongs to the field of energy and metallurgy. Specifically, the invention discloses an iron ore low-carbon electrometallurgy system and method. And the iron ore concentrate is purified through solid phase enrichment, and the impurity content in subsequent electrolyte is reduced. And through reduction acidolysis, the acidolysis efficiency is improved, and low-acid conversion is realized. And through high-temperature desulfurization, resource utilization and sulfur element circulation of acidolysis residues and purification residues are realized. And a high-temperature medium generated by the solar furnace is used for supplying heat for desulfurization, so that low carbonization of energy is realized. High-temperature air is obtained through the sulfur dioxide heat exchanger, the high-temperature air is used for supplying heat to acidolysis and electrometallurgy procedures, and efficient utilization of heat is achieved. The valence state adjustment of the ferrous sulfate solution, the preparation of pure iron, the regeneration of sulfuric acid and the recycling of oxygen are realized through electrometallurgy. The method is suitable for large-scale and continuous low-carbon electrometallurgy of iron ore, and has the advantages of high efficiency, low energy consumption, no pollution, ultralow emission of carbon dioxide and the like.
