Jinchuan Group Co., Ltd., headquartered in Jinchang, Gansu Province, was established in 1959. It is a state-controlled conglomerate under the People's Government of Gansu Province, specializing in mining, mineral processing, smelting, chemical production, and advanced processing. The Group primarily produces nickel, copper, cobalt, gold, silver, platinum group metals, advanced non-ferrous materials, and chemical products. These products are widely applied across modern industries and sectors of the national economy, including construction, machinery, petrochemicals, new energy, battery manufacturing, and biomedicine.
During the 1960s, the trailblazers of Jinchuan struggled through adversity to build China's first nickel, cobalt, and platinum group metals production line, bringing to an end the country's historical shortage of these resources. Following the reform and opening-up period, a nationwide scientific and technological endeavor was launched to ensure the comprehensive utilization of Jinchuan's resources. Jinchuan was then listed as one of China's three major bases for the comprehensive utilization of mineral resources, marking the beginning of its transformation into a technology-driven enterprise.
Entering the 21st century, Jinchuan has leveraged both domestic and international markets and resources to achieve rapid growth in comprehensive strength. Since 2018, the Group has fully applied the new development philosophy, advancing efforts to establish a globally competitive, world-class enterprise. It has accelerated high-quality development and entered a new chapter in its pursuit of excellence. As of now, the Group ranks second globally for nickel production, fourth for cobalt production, first in Asia for platinum group metals production, and third in China for copper production. In 2025, Jinchuan ranked 235th on the Fortune Global 500 list and 59th among the China Top 500 Enterprises.
Jinchuan Group engages in the development of non-ferrous metal resources and the promotion of industrial, technological, and supply chain collaboration across 20 provinces and cities in China and over 30 countries worldwide. Its six major business sectors are: Jinchuan Nickel and Cobalt, Jinchuan Copper and Precious Metals, Jinchuan Science and Technology, Jinchuan New Materials, Jinchuan New Energy, and Jinchuan Scientific and Technological Innovation. The Group has established a comprehensive industrial chain that spans resource development, metallurgy, new materials, new energy, and chemical production.
The Group boasts two national-level innovation platforms, the National Key Laboratory for the Development and Comprehensive Utilization of Nickel-Cobalt Associated Resources and the National Engineering and Technology Research Center for Nickel-Cobalt New Materials. It also established Gansu Province's first Academician and Expert Workstation within an enterprise.

TYF Machinery has pioneered a reinforcing mesh welding machine, which boasts longitudinal reinforcement spacing stepless-adjustment, resolving the construction industry's longstanding reliance on manual rebar tying. This innovation can produce 400+ daily variants of composite slab and wall panel meshes, eliminating the need for over 40 workers engaged in rebar detailing, processing, tying, and inspection. It was honored with the "Customer-Favorite New Equipment Award" at the 2023 China Concrete Exhibition's New Tech/Product/Equipment Promotion Conference.
Through expert evaluation organized by Hubei Technology Exchange, its core technologies were certified as "internationally leading". TYF Machinery co-authored the milestone industry textbook "Intelligent Processing Technology for Reinforced Steel Products" with the Architectural Society of China, CSCEC Science & Technology, and Hebei University of Technology. This prefabricated construction training manual serves as essential reference for equipment selection by technical and managerial professionals.
TYF Machinery established a Digital Twin Smart Manufacturing Center with Hebei University of Technology, developing an AI-powered cloud platform that automatically: Converts CAD drawings into machine-executable processing instructions; Transforms design data into material codes for MES integration. This feature eliminates massive manual data entry. The platform won the Grand Prize at the 2nd "New Infrastructure Cup" China Intelligent Construction & BIM Application Competition.
TYF's CNC rebar processing equipment has been included in the Third Batch of Key Products, Equipment, and Technical Services Recommended for the Belt and Road Initiative.
