        The cyclic metallurgy process refers to a metallurgical process that can economically and efficiently extract valuable metals and realize the recycling of the chemical raw materials and water used in the process,and can reduce or avoid the generation of waste water,waste gas and waste residue.With the economic transformation and development of the country,the ecological civilization construction and environmental protection work in depth,the smelting industry faces severe challenges,and many traditional metallurgical processes have to be transformed and upgraded.In this paper,the recovery of vanadium,chromium and sodium carbonate from the leach solution of roasted vanadium slag,the separation of copper and nitric acid from nitric acid deplating solution,and the removal of arsenic,antimony and bismuth from copper electrolyte were taken as examples to introduce the development and application of cyclic metallurgy process.
