In industrial production, the treatment of waste acid has long been a critical challenge for both environmental protection and cost control. Whether in chemical processes such as nitration and sulfonation, or in industries like steel, titanium dioxide manufacturing, and metal…

In high-tech industries such as LCD panels, semiconductor materials, and photovoltaic cells, indium is an indispensable “vitamin.” However, primary indium resources are scarce and expensive. With the surge in electronic waste—such as discarded LCD screens and ITO target scraps—the value…

In the field of non-ferrous metal smelting, separation and purification have always been critical steps that determine product quality and production costs. With declining ore grades and increasingly stringent environmental requirements, traditional extraction technologies face numerous challenges, such as low…

With the rapid development of the new energy industry, the demand for lithium resources continues to rise. However, the vast majority of lithium is found in salt lake brines, which commonly exhibit a high magnesium-to-lithium (Mg/Li) ratio. The separation of…

In the production of fine chemicals involving alkali washing and water washing, the purification and recovery of organic solvents are critical factors determining both product quality and production costs. Especially for key solvents such as benzene and xylene, the traditional…

In industries such as petroleum, chemical, pharmaceutical, and pesticide manufacturing, N,N-dimethylacetamide (DMAC), as a high-performance polar solvent, is widely used in the production of cephalosporin antibiotics, amoxicillin, and other pharmaceuticals, as well as in the manufacture of coatings, plastic films,…
