With the rapid development of the new-energy industry, efficiently recovering valuable metals such as nickel and cobalt from spent lithium batteries has become a crucial step in resource regeneration. Faced with the surging volume of retired batteries, how to efficiently,…

In chemical production, washing extraction is a key step that directly affects product purity, operational efficiency, and cost control. Traditional reactors, though widely used, suffer from several limitations—batch operation, low separation efficiency, large footprint, and high solvent consumption—now becoming bottlenecks…

In numerous industrial sectors such as metallurgy, electroplating, battery manufacturing, and titanium dioxide production, the treatment and recycling of waste acid have long posed challenges that involve both environmental pressures and economic burdens. Among these challenges, the efficient and economical…

Each ton of waste circuit boards contains up to 30% base metals and 0.4% precious metals, with copper, gold, silver, and palladium being particularly valuable. Improper disposal of this discarded electronic waste will severely pollute soil and groundwater; however, scientific…

In the production of lubricant base oils, furfural refining is a crucial core process. Its purpose is to selectively separate desirable components (saturated hydrocarbons) from undesirable ones (aromatics, resins, and other impurities) in vacuum side line oil, thereby improving the…

Crude nickel sulfate raw materials contain various metallic impurities such as iron, copper, and zinc, as well as free acids. To achieve efficient purification, extraction is currently the most ideal process route. This technology, through a series of processes including…
