In the context of the increasing importance of resource recycling, vanadium, as an important strategic metal, plays a key role in the fields of steel, new energy, aerospace, etc. More than 90% of the world’s vanadium is used in the…

As global environmental regulations become increasingly stringent and demand for resource recycling increases, waste lubricating oil regeneration technology is facing major changes. N-methylpyrrolidone (NMP) has become a common solvent in waste lubricating oil refining processes due to its excellent solubility…

Using centrifugal extractor to extract and recover dimethylformamide (DMF) from wastewater is an advanced technology that is efficient, fast and suitable for continuous production. The core is to use centrifugal force to accelerate the mixed mass transfer and rapid separation…

At a time when the global green transformation and resource recycling strategy are accelerating, the strategic value of platinum-based precious metals (including six elements such as ruthenium, rhodium, and palladium) is becoming increasingly prominent. These rare metals, known as “industrial…

Although the hydrometallurgical zinc smelting process occupies a dominant position in global zinc production, it faces severe challenges in processing high-iron zinc roasted sand. The stable spinel structure of zinc ferrite leads to a significant negative correlation between the leaching…

As a basic chemical raw material, acetic acid has always faced technical challenges in the treatment of wastewater generated during its production and use. In response to the problem of equipment for treating acetic acid wastewater with different concentrations, the…
