en.Wedoany.com Reported - China Henan Yuguang Gold & Lead Co., Ltd. (hereinafter referred to as "Yuguang") recently broke ground on its advanced rare and precious materials manufacturing project in the Kongshan area of Jiyuan City, Henan Province, officially commencing site leveling works. This project marks Yuguang's third "mountain-based plant construction" since 2008, signifying another leap from traditional smelting to high-end new materials.
Yuguang Gold & Lead is a leading lead and zinc smelting enterprise in China, headquartered in Jiyuan City, Henan Province. Since 2008, Yuguang has embarked on a development path of "moving industry out of the city, projects onto the mountains." In 2008, Yuguang first relocated and expanded its operations by building China's first direct lead smelting production line, which won the second prize of the National Science and Technology Progress Award. In 2011, the company undertook a second expansion, constructing the Yuchuan plant area, upgrading the copper smelting sector, and forming a coordinated development pattern for lead, zinc, and copper. Now, with this third deployment in the Kongshan area, Yuguang leverages another technological achievement that won the second prize of the National Science and Technology Progress Award to enter the new field of advanced rare and precious materials.
Rooted in national strategic needs, the project focuses on the deep processing of rare and precious metals. Since 2026, facing multiple challenges such as cumbersome project approvals, massive rock excavation volumes, and tight timelines, all Yuguang employees have adhered to the principle of "no day can be delayed, no day can be slackened" to advance the project. In the second half of 2025, the company successfully completed the land real estate certificate for the project. In March 2026, Yuguang Design Institute initiated the scheme design. From March to April, the project efficiently completed preliminary works including red line verification, geological survey and mapping, seedling clearing, and grave relocation. On May 1, the online auction for rock disposal operations was successfully concluded.
Liu Suhong, technical lead of Yuguang Design Institute, introduced that the project, drawing on the design experience of the 5,000-ton/year anode slime project and over a decade of smelting production practice, incorporates advanced equipment technologies such as oxidation lances and permeable bricks on the basis of mature processes. It optimizes the pyrometallurgical process for anode slime, achieves fully automated production for gold and silver refining, and full hot-state intensified smelting for antimony and bismuth smelting. Simultaneously, it accomplishes fundamental control of low-altitude fugitive dust emissions and intelligent unmanned upgrades for plant logistics. The project is constructed in collaboration with participating units including Henan Yuda Industry and Trade Co., Ltd. and China Construction Seventh Engineering Bureau. This project represents a significant move for Yuguang Gold & Lead in its transformation from traditional smelting to high-end new materials, helping to enhance China's self-sufficiency capability in rare and precious metal materials.
