Control the temperature, chlorine partial pressure, and pressure to selectively separate Au, Cu, Sn, Fe, Ni, etc. through chlorination volatilization.
Urban mines contain a complex mixture of valuable metals and base metals such as Au, Cu, Sn, Fe, and Ni. When separating and recovering these through wet processing, challenges may arise related to the use of reagents, waste liquid treatment, pretreatment processes, and drying processes. Our small chlorine furnace can selectively separate and recover metal components by converting them into volatile chlorides through dry chlorination using Cl2/HCl, while controlling temperature, chlorine partial pressure, and pressure. For example, in the low-temperature range, easily volatile chlorides such as FeCl3 and SnCl4 can be removed first, and in the mid-temperature range, the separation of precious metals can be considered using the vapor pressure differences of AuCl3 and others. 【Features】 ■ Supports dry chlorination and chloride volatilization using Cl2/HCl ■ Allows for selective separation of multiple metals such as Au, Cu, Sn, Fe, and Ni ■ Accommodates staged processing with controlled temperature, chlorine partial pressure, and pressure ■ Reduces waste liquid and drying processes associated with wet processing ■ Enables exploration of urban mine recycling conditions with small sample sizes *For more details, please download the materials or contact us.
