Mechanism and application of the ore with chlorination treatment: A review

As a very effective metallurgical method for processing complex metal minerals, Chlorination metallurgy has been widely used in the metallurgical industry. In this paper, the chlorination agents used in the process of chlorination metallurgy were summarized as gaseous chlorination agents and solid chlorination agents. the advantages and disadvantages of each of them were compared and analyzed, and the main mechanisms involved in the process of chlorination roasting and chloride separation were discussed and analyzed, respectively; The research results of related scholars on chlorination metallurgy were summarized, and the application progress on sulfide ores, oxidized ores, wolframite concentrates and rare earth ores was introduced in detail, and from the perspective of thermodynamics, the feasibility of treating complex metal ores with chlorination metallurgy was analyzed, in order to provide some help and reference for the subsequent research and application of chlorination metallurgy.
