Development and Application of Cyclic Metallurgy Process
-
摘要: 循环冶金工艺是指,既可经济高效提取有价金属,又能实现工艺过程所用的化工原料及水的循环利用的冶金工艺,是从源头上减少或避免“三废”产生的冶金工艺。随着国家经济转型发展,生态文明建设及环境保护工作的深入进行,冶炼行业面临严峻的挑战,许多传统冶金工艺不得不转型升级。以钒渣提钒液分离回收钒铬及碳酸钠,硝酸退镀液分离回收铜和硝酸,及铜电解液自净化分离回收砷、锑、铋为例,介绍循环冶金工艺的开发与应用。Abstract: 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.
