Advances in Solvent Extraction Metallurgy and Metal Recovery

Dear Colleagues,

The increasing demand for efficient metal recovery and the gradual replacement of traditional extraction technologies by green and advanced processes remain prominent trends, which also serve as important drivers for the development of extractive metallurgy. This Special Issue focuses on the advances in solvent extraction metallurgy, including the control and optimization of extraction processes, the design and application of novel extractants, and the analysis of metal recovery efficiency and product purity. Since its inception, solvent extraction has been widely used for separating and recovering metals from complex ore matrices and secondary resources that are difficult to handle by other extraction methods. Its advantages of high selectivity, energy efficiency, and easy continuous operation have attracted extensive attention, expanding its potential applications in the recovery of strategic metals, precious metals, and non-ferrous metals. The controllable selectivity of extractants and the adjustable process parameters, which directly affect the metal recovery rate and environmental friendliness, make solvent extraction metallurgy highly competitive in the field of metal recovery. For these reasons, the solvent extraction process itself is of great significance to the efficient utilization of metal resources, which can be realized through single-stage or multi-stage operations. Based on the regulation of extractant concentration, temperature, and phase ratio, as well as the assistance of innovative technologies such as ionic liquids and synergistic extraction systems, high-purity metal products can be obtained without complex post-treatment.

This Special Issue welcomes articles focusing on the optimization of solvent extraction processes and their influence on metal recovery efficiency and product quality, whether in the extractant design stage or the process operation stage. Environmentally friendly, low-cost, and high-efficiency processes are particularly concerned, which have high application potential in advanced solvent extraction metallurgy and metal recovery, contributing to the sustainable development of the metallurgical industry.
