New Ideas for the Design of Green Smelting Project of Domestic Lead and Zinc Resources

摘要

During the past 15 years, through independent research and development and innovation, a thorough review and assimilating information of this industry showed that the lead and zinc smelting technology in China's non-ferrous industry has experienced many historical turning points. Especially in the past five years, under the dual pressure of resources and environmental protection, the lead and zinc smelting industry has continuously upgraded and reformed the existing technologies and equipment, greatly improving the level of technical equipment in the industry, with the enhancement of sustainable developments in the industry. This is demonstrated in this paper through the following lead-zinc smelting process examples: the innovative and industrialized zinc-oxygen pressure leaching process and associated equipment; the research and development and upgrading of three-continuous furnace bath smelting technologies, and associated equipment and by the introduction and adjustment of lead smelting technologies and equipment from abroad. All of above have the intention to establish the twofold transformation between gold mine and green mine, as quoted by Xi Jinping, who focuses on the synergy of environmental and industrial effect. For this purpose, this paper summarizes and analyses the whole life cycle of the project from investigation and establishment to design and construction, and then to commissioning and operation, and puts forward new ideas for the design of green smelting project of domestic lead and zinc resources.
