In vanadium extraction processes, whether using the traditional sodium roasting-acid leaching method or the novel salt-free roasting-acid leaching method, the final step involves an extraction process to achieve efficient separation and purification of vanadium. The CWL-M centrifugal extractor, based on…

In the development of hydrometallurgical processes, scaling up from laboratory research to industrial production is a critical step that often determines the success or failure of a project. The CWX-J Series laboratory mixer settler, independently developed by Zhengzhou Tiei Extraction,…

In many industrial fields such as chemical processing, pharmaceuticals, environmental protection, and hydrometallurgy, liquid liquid extraction is a core technology for separation and purification. Its efficiency and economic performance directly influence the overall competitiveness of production lines. Traditional equipment, such…

In the production workshop of a fine chemical enterprise, a mature process is operating steadily. A complete sequence—two stages citric acid washes, two stages alkaline washes, and two stages water washes—is repeated cycle after cycle in a 30-cubic-meter reactor. Although…

In various industrial fields such as chemicals, pharmaceuticals, and dyeing, dimethylformamide (DMF) is widely used as an important organic solvent. However, high-concentration DMF wastewater (with concentrations of 1%–20%) generated during production presents significant treatment challenges due to its complex composition,…

In liquid–liquid extraction processes, the operational stability and separation efficiency of centrifugal extractor are critical, and phase entrainment is a core issue that directly affects product quality and yield. The operating principle of a centrifugal extractor mainly consists of two…
