Cadmium Depth Separation Method in Polymetallic Sulfate Solution: Flow-Electric Field Enhanced Cementation Combined with M5640 Extraction

An efficient and controllable process for separating copper cadmium was required to be developed due the high cost of long separation slag generated from zinc smelting process. Therefore, a new application deep by combining Circulating Flow Electric (CFE) cement method 2-hydroxy-5-nonyl formaldehyde oxime (M5640) extract method. The firstly removed ions utilizing M5640 obtained primary purification solution, followed CFE in depth. effects extractant volume fraction, pH, Oil phase/Aqueous phase (O/A) ratio reaction time on removal were investigated. results showed that above 97%, while below 1.6%, respectively, proved selectivity significantly higher than metals such as zinc. characterization indicate oxygen hydroxyl group nitrogen co-ligated with subsequently formed chelated extracts. That mechanism ion M5640. Furthermore, extraction purity carried out residual liquid. A novel enhanced coupling an electric field circulating flow applied sulfate solutions. optimal conditions explored, which further fitted into statistical equations optimized response surface analysis. Since theoretical close experimental results, optimization considered effective. parameters 6.23 mL/s rate, 48.14 mA/cm2 current density, 2.25 0.93 anode/cathode area ratio, respectively. Next, electrical efficiency, its weight distribution cell sponge under different fields calculated measured. analyzed prove existence interval high-speed field.
