Copper, nickel, and cobalt are important metals for strategic industries such as new energy batteries and superalloys. They are often associated with sulfide ores or laterite nickel ores. To obtain high-purity copper, nickel, and cobalt products, solvent extraction and separation…

Naphthalene-based sulfonic acid compounds are important intermediates in the dye industry and are widely used in the production of reactive dyes, acid dyes, mordant dyes, and other products. However, during the production of naphthalene-based dye intermediates, large amounts of wastewater…

In high-end industries such as semiconductors, OLED, DRAM, sensors, and hydrogen energy, the demand for platinum group metals (PGMs) such as ruthenium, iridium, and platinum continues to grow. Their supply is highly concentrated in South Africa and Russia, while ruthenium…

Xylene is a product in which two hydrogen atoms on the benzene ring are replaced by methyl groups. It exists in three isomers: ortho-xylene, meta-xylene, and para-xylene, and industrially, the term “xylene” generally refers to a mixture of these three…

Against the backdrop of continuously growing global demand for long-duration energy storage, vanadium redox flow batteries (VRFBs) are becoming an important technology route for large-scale energy storage, thanks to their inherent safety, long cycle life, scalable capacity, and recyclable electrolyte.…

Salt lake brine is not only an important source of lithium, but also contains scarce strategic metals such as rubidium and cesium. Rubidium and cesium play irreplaceable roles in high-end fields including optoelectronic materials, specialty glass, energy conversion, and aerospace.…
