Abstract: The green upgrade of the chemical metallurgy manufacturing industry needs to start from the innovation of cleaner production technology. Research and development of efficient, green and reasonable utilization of major characteristic resources are the keys to realizing the sustainable development of resources and environment. Cleaner production is the best pattern of pollution preventing and the only way to achieve sustainable development and recycling economy. The sub-molten salt media clean chemical metallurgical generic technology created by Professor Yi Zhang, academician of Chinese Academy of Engineering (CAE), has realized the efficient clean conversion and separation of refractory amphoteric metal minerals with chemical commonality (including Al, Cr, V, Ti, Mn, Nb, Ta, etc.). Reactive oxygen species have been considered as the key factor to realize the efficient conversion of amphoteric metal mineral resources. The sub-molten salt media chemical system with the reactive oxygen species tuning as the core technology was established. The reactive oxygen species tuning strategy in the sub-molten salt media is summarized into five methods, including chemical field enhancement, flow field enhancement, pressure field enhancement, additive enhancement, and microbubble enhancement. All the above methods can be applied to strengthen the decomposition of amphoteric metal mineral resources and decrease the reaction conditions. Till now, the sub-molten salt technology has been successfully applied to the treatment of vanadium titano-magnetite, chromite, diasporic bauxite, tantalum-niobium ores, and high-alumina fly ash. Furthermore, as a feasible, efficient, easy operation and environment-friendly method, electrochemistry plays a vital role in various fields including metallurgy, chemical engineering, and catalysis. Based on the basic research of reactive oxygen species by electrochemical method in our group, novel alkaline electrochemical advanced oxidation processes with electrochemical reactive oxygen species tuning technology were proposed, which provides theoretical and technical support for the application of the reactive oxygen species tuning technology in metallurgy, resources and environment fields.
