| Abstract: | The paper describes the study on processes for recovering cadmium from zinc concentrate roasting dust collected by electrostatic precipitator (ESP), including comparison of three cadmium leaching processes, i.e. water leaching, acid leaching and oxidation acid leaching points out that the oxidation acid leaching-arsenic removal-cementation-briquetting-casting is an optimal process for recovering cadmium from cadmium-bearing dust collected by ESP, where the cadmium leaching efficiency can be higher than 90% and grade of crude cadmium can reach 99.10%. |
