Jilin Jien Nickel Industry Co., Ltd. (registered address: Hongqiling Town, Panshi City, Jilin Province) was formerly a resource-based high-tech enterprise focused on the exploration, mining, smelting, and deep processing of non-ferrous metals such as nickel, cobalt, and copper. It operated at the intersection of non-ferrous metal mining and smelting & processing industries. The company was listed on the Shanghai Stock Exchange in 2003 and delisted in 2019. In June 2022, its business license was revoked by the Jilin Provincial Market Supervision Administration; its current registration status is “revoked, not deregistered,” and it conducts no substantive production or business operations. Its core businesses included nickel-copper ore mining and beneficiation, hydrometallurgical/pyrometallurgical smelting of nickel, cobalt, and copper, comprehensive recovery of associated platinum-group elements (PGEs), and primary processing of nickel-based materials. Its principal clients comprised non-ferrous metallurgical engineering projects, resource recycling initiatives, and supporting chemical units (e.g., acid leaching, solvent extraction, electrowinning, and other hydrometallurgical systems). Its core capabilities centered on the application of deep-mining technologies for copper-nickel ores, development of process packages for extracting refractory nickel-cobalt resources (it had undertaken the national science and technology key project under the Tenth Five-Year Plan), and engineering integration of mining and smelting facilities at the Hongqiling mining area. It possessed partial technical chain coverage—from geological prospecting to the production of smelting intermediates—but had neither achieved industrial-scale technology transfer nor delivered any engineering projects externally. Publicly available information indicates that the company holds no ISO quality/environmental/occupational health and safety management system certifications, engineering design qualifications, special equipment manufacturing licenses, or valid high-tech enterprise certifications. The industry standard YS/T 248.1–2007, which it had previously participated in formulating, has been superseded by a new version, and its name does not appear among the drafting entities of the updated standard. Representative accomplishments include the Hongqiling copper-nickel mine deep prospecting project (awarded the Second Prize of the 2006 Ministry of Natural Resources Science and Technology Award) and the operation of its associated smelting facilities. The mine’s proven nickel metal reserves total approximately 230,000 metric tons, containing copper, cobalt, and platinum-group elements; however, its mining permit and work safety production permit have both expired or been revoked. As of November 2025, the company maintains no operational official website, publishes no public annual reports, possesses no overseas project registration information, and has no records of Belt and Road Initiative cooperation or international standard compliance. Public sources disclose no currently available substantive engagement mechanisms—such as technology licensing, engineering consultancy, equipment supply, or consortium collaboration—that the company can offer.
