We are theoretically examining a new approach to selectively volatilize and recover specific metals from systems containing multiple metals through precise control of "temperature × pressure × chlorination reaction."

The "chlorine furnace" we handle has a structure that allows for independent control of temperature and chlorine partial pressure under reduced pressure. Urban mines contain metals such as Au, Cu, Sn, Fe, and Ni, which coexist in a complex manner. If these can be separated using the dry chlorination volatilization method, it would be possible to realize a new recycling method that efficiently recovers valuable metals while reducing the burden of wastewater treatment. Furthermore, due to the characteristics of this device, which can precisely control temperature, pressure, and chlorine partial pressure, we believe it could develop into "selective recovery of valuable metals from urban mines" in the future. 【Features】 ■ Volatilization of base metals at low temperatures: Selective volatilization of FeCl3, SnCl4, etc., around 200-300°C ■ Control of noble metal salt generation at medium temperatures: Separation of noble metals using stable regions such as AuCl3 ■ Reaction sequence switching through pressure control: Control of the generation and decomposition equilibrium of chlorides under reduced pressure conditions *For more detailed information, please download the materials or feel free to contact us.
