New Ideas for the Design of Green
Smelting Project of Domestic Lead
and Zinc Resources
Cui Chen, Xingmin He and Hua Bai
Abstract 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.
Keywords Demonstrative lead–zinc smelting process · Three-continuous furnace

transformation · Design of green smelting project
Introduction
China is rich in Pb and Zn mineral resources and globally the largest country in
smelting and consumption of both metals. With the rapid economic development,
