        China has a large amount of solid waste, and its composition is complex, containing a large amount of valuable metals. Its resource recycling, separation and purification have become a major environmental problem in China. With the goal of solid waste reduction and high-value metal recovery, this direction is aimed at Jiangxi's characteristic resources such as copper, tungsten and rare earth, and large quantities of spent lithium-ion batteries. The new principles and technologies for harmless, reduction and resource utilization of tailings, smelting slag/smoke dust are studied, and the technologies and equipment of harmless and resourceful recovery of smelting slag/smoke and dust are developed. The systematic innovation of theory, method, technology and equipment are achieved. A new method of enhancing metal leaching efficiency in solid waste by valence oxidation, three-phase extraction and field is invented, and the mechanism of enhancing selective separation ability by means of crystallization ability, ion complexation and space matching control is proposed. The new technologies of inducing high efficiency impurity removal, grouping impurity removal, multistage fractionation purification and imprinted cavity selective adsorption separation are invented. These technologies opened a selective recycling mode for the utilization of polymetals in solid waste, realized a leap in the purity of metal anions and cations from 2N to 6N, reversed the pure input solid waste disposal mode, and developed a new profitable way for solid waste treatment. It is recommended by China Nonferrous Metals Industry Association as the best feasible technology for multi-metal resource recycling in solid waste. The related technical achievements have been applied to more than 20 enterprises such as tungsten, rare earth and waste lithium battery recycling, and have produced significant economic, environmental and social benefits, which have greatly promoted the green transformation of the industry.
